Saint Isaac’s Cathedral: tickets, prices and opening hours

Saint Isaac’s Cathedral is the most imposing church in St. Petersburg and an absolute must if you’re visiting the city. In this article I’ll walk you through what’s worth seeing inside, how much a ticket costs in 2026, why you can simply buy it at the box office with no fuss, and why climbing to the colonnade for that bird’s-eye view of St. Petersburg is so worth it.

This is step 5 of my guide to planning a trip to Russia in 10 steps, where you’ll find everything else in order.

1. The essentials in 30 seconds

2. Four cathedrals on the same spot

What you see today isn’t the first church dedicated to Saint Isaac of Dalmatia in St. Petersburg, but the fourth. And each of them tells a different chapter of the city’s history.

The first was a humble wooden chapel built in 1710 across from the Admiralty, almost on the Neva’s bank. It was a modest structure, an old “izba” (drafting hut) converted into a chapel, where in 1712 Peter the Great married his second wife, Catherine Alekseyevna. The tsar had been born on Saint Isaac of Dalmatia’s feast day — a 4th-century Byzantine monk — and wanted his patron saint to have his own church in the new capital.

In 1717 it was decided to replace the chapel with a stone church. Construction was begun by Georg Mattarnovi and continued by architects such as Trezzini and Zemtsov, but the building’s foundations were poor because of the proximity to the river, and in 1763 it had to be demolished. Catherine the Great commissioned the third version from the Italian architect Antonio Rinaldi: an ambitious baroque project with five domes and a bell tower, but poorly completed. When Paul I rushed to finish it, the result was a disproportionate church that clashed with the imperial centre.

Alexander I decided to settle the matter once and for all. In 1809 and 1813 he held competitions to “rebuild” the church. Established architects like Quarenghi, Voronikhin and Cameron took part, but the winner was a virtually unknown young Frenchman: Auguste de Montferrand.

3. Montferrand and 40 years of construction

When construction began in 1818, Montferrand was 30. When the cathedral was consecrated in 1858, he was 70. The project literally consumed his entire adult life and, according to legend, he had been told he would die when it was finished: he fell ill during the consecration itself and died a few days later. He wanted to be buried inside the cathedral, but Alexander II refused permission and his remains ended up in the Montmartre cemetery in Paris.

Building a temple of this scale on St. Petersburg’s swampy ground was no easy feat. The foundations, a 7.5-metre-tall block of masonry, were laid on 24,000 wooden piles driven into the earth. The scaffolding and the pulley system used to raise the columns were designed by the Spanish engineer Agustín de Betancourt: a system of 16 capstans that allowed 128 workers to raise a 17-metre, 114-tonne column in just 40 to 45 minutes. The first of the 48 columns of the portico was hoisted into place on 20 March 1828, in front of Tsar Nicholas I and a crowd of curious onlookers and foreign scientists.

The cathedral’s figures are those of a building that’s simply off the scale: 101.5 metres tall, 111.2 long, 97.6 wide. Over 4,000 m² of interior surface. 112 columns of pink Finnish granite, quarried at Pyterlahti near Vyborg. The exterior dome is 25.8 metres in diameter and is one of the first in the world built with a metal frame (490 tonnes of iron, 990 of cast iron, 49 of copper and 30 of bronze). Its gilding, applied between 1838 and 1841 using the fire-gilding technique, cost the lives of 60 workers who died from mercury vapour poisoning.

And even then, the numbers don’t quite capture the feeling of standing in front of it. The façade is grey marble, the steps are granite, the doors are oak and bronze. And once you step inside, everything changes.

4. What to see inside the cathedral

The first thing that strikes you on entering is the sheer luxury of the materials. More than 40 different minerals were used in the decoration: Russian, Italian and French marbles for walls and floors, malachite and lapis lazuli for the iconostasis columns, granite for the plinth. In total, 400 kilos of gold were used (100 just for the dome, 300 for the interior).

The cathedral has three altars: the main one is dedicated to Saint Isaac of Dalmatia; the one on the right, to Alexander Nevsky (the city’s patron saint); and the one on the left, to Saint Catherine. The iconostasis, which takes up the entire front wall of the main altar, is over 1,000 m² in size and is flanked by green malachite columns and, in the central part, by deep-blue lapis lazuli columns. Behind the iconostasis’s royal doors there’s a stained-glass window showing Jesus Christ in a red tunic: extremely unusual in an Orthodox church (stained glass is usually associated with Catholic Gothic), made by German masters using multi-layered glass.

Look up. The dome was painted by Karl Bryullov, the same artist who painted “The Last Days of Pompeii”. It’s one of the largest works of Russian classicism, 816 m² that took four years to complete. At its centre, the Virgin Mary appears in glory, surrounded by patron saints of the Romanov dynasty. Hanging from the dome is a silver dove symbolising the Holy Spirit: it weighs 84 kilos and has a wingspan of over two metres. Right beneath it, until just a few years ago, hung the famous Foucault pendulum that the Soviets installed in 1931 to prove the Earth’s rotation when they turned the cathedral into the Museum of Atheism.

Around the dome’s drum, 12 statues of angels watch over you, and between them, 12 apostles. The sculptures, despite their size, are surprisingly light: they were made using the galvanoplasty technique, hollow on the inside. It’s one of the many 19th-century engineering details Montferrand built into his work.

The walls are covered in 103 frescoes and 52 paintings on canvas, plus 62 mosaic icons made with the Florentine technique, assembling semi-precious stones until they form a perfect image. From a distance they look like paintings; up close, you realise they’re a jigsaw of minerals.

A detail almost nobody notices: on the frieze of the western pediment, next to the inscription “To the King of Kings”, there’s a figure on the left who isn’t bowing to Saint Isaac and is holding a model of the cathedral in his hand. It’s Montferrand himself, self-portrayed in his own work.

Another story worth knowing: during the Siege of Leningrad in World War II, the cathedral was used as a warehouse for the artistic treasures evacuated from the museums on the outskirts (Peterhof, Tsarskoye Selo, Pavlovsk). Soldiers painted the gilded dome grey so it wouldn’t serve as a reference point for German bombers. The shells didn’t hit the building directly but shrapnel left marks on the columns of the west portico, which have been deliberately preserved as a reminder. If you look closely, you can still see them.

5. Climbing to the colonnade: the best view of St. Petersburg

If you only have time for one thing, climb the colonnade. The cathedral’s panoramic viewing platform sits 43 metres above ground, ringed by the 24 columns that hold up the dome’s drum. For more than a century it was the highest point a tourist could climb to in St. Petersburg, and the view is still spectacular: the Admiralty, the Neva, the Winter Palace and the Hermitage, the spire of the Peter and Paul Fortress, the gilded domes and the drawbridges on the horizon.

To reach the top you have to climb 262 steps up two spiral staircases — no lift. The space is narrow and enclosed, not suitable for people with mobility issues or severe claustrophobia, but perfectly manageable if you take it slowly. The colonnade ticket doesn’t offer discounts for anyone (no children, no senior rates): everyone pays the same.

The real trick is the summer schedule. From 1 May to 30 September, the colonnade also opens at night, from 18:00 to 21:30. If you go up during the White Nights (June and the first half of July), the sun barely sets: you’ll see St. Petersburg bathed in that endless golden light that only exists here. If you can, plan it that way.

6. Updated prices in 2026

These are the official prices listed on the museum’s website as of 2026 (in Russian rubles):

	Adult	Youth 7-18	Under 7
Museum entry (daytime)	550 ₽	300 ₽	Free
Museum entry (night session, May-Sep)	700 ₽	700 ₽	700 ₽
Colonnade (daytime)	600 ₽	600 ₽	600 ₽
Colonnade (night session, May-Sep)	700 ₽	700 ₽	700 ₽
Audio guide (English, Spanish, etc.)	300 ₽	300 ₽	300 ₽

At the current exchange rate, the standard museum ticket comes out to around €6, the colonnade another €6.50, and the audio guide adds about €3.50. The full visit (cathedral + colonnade + audio guide) totals 1,450 rubles, roughly €16. Very reasonable given the historic and artistic weight of the place.

A quick note on discounts: if you have an ISIC card (international student ID), museum entry drops to 330 ₽. But the senior and student discounts only apply to Russian or Belarusian citizens with proof of ID. As a foreign tourist, you’ll most likely pay full price unless you carry an ISIC.

7. How to buy tickets (and why I’d recommend the box office)

Tickets can perfectly well be bought at the cathedral’s box office. I’ve been to St. Petersburg several times and I’ve never run into significant queues to get in, not even in high season. The box office is right next to the main entrance, and the line moves quickly.

What about buying online? The official page is isaak.ticketnet.ru and it technically works, but the problem is payment: it only accepts Russian cards (MIR) and Russian payment methods like SBP (Fast Payments System). Foreign Visa and Mastercard cards don’t work in Russia since March 2022. Unless you have a Russian MIR card, buying online won’t work for you.

Luckily, you don’t need to. These are the real options for a foreign tourist:

• At the box office, in cash (rubles): the safest option. You’ll need to have exchanged money beforehand (I cover the details in my guide on how to pay in Russia).
• At the box office, with a Russian MIR card: if you’ve come prepared and have a MIR card in your name, you can pay with it.
• Guided tour with a local guide: the most convenient option for foreigners. The guide buys the tickets and you don’t have to deal with cash or struggle with the Russian-only box office. I cover this in detail in the article on guided tours in St. Petersburg.

To play it safe, keep in mind that at the box office you can buy combined tickets (cathedral + colonnade) or separately. I’d recommend getting both: inside you have the art and the marbles; up top, the city. The price difference is small and the two experiences are very different.

8. Detailed cathedral opening hours

A lot of people get confused with the opening hours because the cathedral runs as a museum during the day and as a viewing platform (the colonnade) on a separate schedule. Let me break it down:

• Museum (inside the cathedral): every day from 10:30 to 18:00, box office until 17:30. Closed on Wednesdays and on 1 January.
• Museum evening session: from 1 May to 30 September, from 18:00 to 21:30 (box office until 21:00). No official guided tours. Closed on Wednesdays.
• Colonnade (viewing platform): every day from 10:30 to 18:00. From 1 May to 30 September it doesn’t close any day. From 1 October to 30 April it closes on the third Wednesday of each month and on 1 January.
• Colonnade evening session: from 1 May to 30 September, from 18:00 to 21:30 (box office until 21:00), every day without exception.

As you can see, summer is by far the best time to visit, because you can do the colonnade at night and take advantage of the extended hours. In winter the hours are stricter and you need to watch out for the Wednesday closures.

9. Religious services: attending mass at Saint Isaac’s

Although the cathedral officially is a museum (it has been since 1931), since 1990 services have been held every day except Wednesday. You can perfectly well attend an Orthodox service inside the cathedral, whether you’re a believer or simply curious.

The usual service times are:

• 8:00: confession and Divine Liturgy (Monday to Saturday).
• 8:30: Divine Liturgy on Sundays and holidays.
• 17:30: Vespers (evening service).

Services take place at the left side altar (dedicated to Saint Catherine) during the week, and at the main altar on Sundays and major feasts. Access to attend the service is free (you don’t need a museum ticket), but you must dress appropriately: shoulders and knees covered, women with their heads covered by a scarf.

The full schedule of services is published on the parish website and on its Telegram channel, both in Russian. If your visit coincides with a major Orthodox holiday (Russian Christmas on 7 January, Easter, Pentecost, the Dormition of the Virgin on 28 August), the atmosphere is especially solemn and well worth it.

10. How to get to the cathedral

Saint Isaac’s Cathedral is right in the centre of St. Petersburg, on the square that bears its name (Исаакиевская площадь, 4). Directly opposite stands the Mariinsky Palace, seat of the Legislative Assembly, and just a few steps away are the Admiralty and the Bronze Horseman, the famous equestrian statue of Peter the Great.

• By metro: the nearest stop is Admiralteyskaya (line 5, purple). After exiting, follow Malaya Morskaya toward the square — it’s a 5-7 minute walk. If you’re coming from Nevsky, you can also get off at Nevsky Prospekt/Gostiny Dvor (lines 2 and 3) and walk 10-12 minutes.
• By bus: bus routes 3, 10, 27 and the marshrutka K-252 stop at “Исаакиевская площадь” (Saint Isaac’s Square stop). Trolleybuses 5 and 22 and the marshrutka K-306 stop at “Малая Морская”.
• On foot from the centre: if you’re walking along Nevsky Avenue, the most beautiful route is to head down to Palace Square (Hermitage), skirt around the Admiralty through Alexander Garden and emerge directly into Saint Isaac’s Square. It’s about a 20-minute walk along one of the most spectacular routes in the city.

11. Practical tips for your visit

After several visits, these are the things I wish I’d known beforehand:

• How much time to set aside: to see the interior properly, between 1 hour and 1 hour 30 minutes. If you go up to the colonnade, add another 45 minutes (including the queue and the climb). Total: between 2 and 2.5 hours to do it well.
• When to go: early in the morning (10:30-11:30) is when there are fewest people. In summer, the evening session at the colonnade is absolutely magical. Avoid weekends in May and the first half of July if you can.
• Audio guide or human guide: the official audio guide is available in English and rents at the box office for 300 rubles. It’s very thorough and enough for a self-guided visit. If you want to really understand the iconography and history, a local guide makes a big difference.
• What to wear: in summer you can enter the museum area in shorts and a sleeveless top. If you’re attending a religious service, shoulders and knees must be covered; women need a headscarf.
• Photos: you can take pictures freely without flash and without a tripod. Professional photography requires special permission.
• Luggage: large backpacks and suitcases aren’t allowed inside. There’s a free cloakroom in the basement before the security check.
• Accessibility: the cathedral’s ground floor is accessible for wheelchairs, but the colonnade is not (262 steps, no lift).
• What’s nearby: take advantage of being in the area to visit the Bronze Horseman (the statue of Peter I on the banks of the Neva), Alexander Garden behind the Admiralty, and the Church of the Savior on Spilled Blood, 15 minutes away on foot and radically different in style. It’s a great contrast.

If you want to fit the cathedral into a multi-day plan, the article on what to see in St. Petersburg in 1, 2, 3 or 4 days might help — I include it in the first-day itinerary.
