More than twenty churches in St Petersburg are called cathedrals, but only eight matter to a visitor. The difference isn't the architecture, it's how much you pay and how you behave inside: three of the eight are state museums with a ticket desk and a turnstile, five are working parishes with free entry and church rules.
## First work out which it is: museum or church
Museums. St Isaac's Cathedral and the Savior on the Spilled Blood belong to the State Museum "St Isaac's Cathedral": ticket desk, ticket, audio guide, closed on Wednesdays (checked 18.09.2026, source: cathedral.ru). Peter and Paul Cathedral is part of the Museum of the History of St Petersburg, also ticketed (checked 18.09.2026, source: spbmuseum.ru). Here you can take photos, listen to an earpiece and not think about a headscarf.
Working churches. Kazan Cathedral, St Nicholas Naval Cathedral, Smolny Cathedral, Vladimir Cathedral and Trinity Izmailovsky Cathedral are parishes with free entry, but services are held there: phone on silent, speak quietly, filming a service, flash and tripods are forbidden (checked 18.09.2026, source: kazansky-spb.ru). A guide with a group is not admitted without the rector's permission.
Hence the order of the day: museums in the morning, churches in the gap between services, roughly from 12:00 to 17:00.
## Kazan Cathedral: free, twenty minutes, you can't miss it
2 Kazanskaya Square, Nevsky Prospekt metro — the exit brings you right to the colonnade. This is the cathedral of the St Petersburg diocese, the city's main church in church terms (source: kazansky-spb.ru). There are no tickets at all.
Worth your attention: the St Petersburg copy of the Kazan icon to the left of the iconostasis — there is a living queue of locals to it; Kutuzov's tombstone and the captured standards of French regiments.
On weekdays the liturgy is at 10:00, on Sundays at 7:00 and 10:00, the evening service at 18:00 (checked 18.09.2026, source: kazansky-spb.ru). It is best to check visiting times outside services on the day of your visit: the church's schedule can change on feast days and during services.
The dress code here is the strictest of the eight: women — head covered, no lipstick, no shorts, capri pants, short skirts or trousers; men — remove your hat; shoulders and décolleté covered (checked 18.09.2026, source: kazansky-spb.ru). A light scarf in your bag solves the problem. And you can't bring in a backpack larger than 30 × 20 × 15 cm.
## St Isaac's: 700 ₽ to go in and another 700 to go up
4 St Isaac's Square, Admiralteyskaya metro. Ticket — 700 ₽, concession (children 7–18, pensioners, Russian students) — 300 ₽. The colonnade is a separate 700 ₽, and concessions don't apply to it, not even children's (checked 18.09.2026, source: cathedral.ru).
Open from 10:00 to 18:00, ticket desk until 17:30, closed on Wednesdays. From 1 May to 30 September there are evening sessions 18:00–21:30 without tours: cathedral 800 ₽, colonnade 800 ₽, audio guide 300 ₽ (checked 18.09.2026, source: cathedral.ru).
The colonnade is 43 metres up, you go up and down on foot only, there is no lift. In summer it is open every day, and from 1 October to 30 April it closes on the third Wednesday of the month (checked 18.09.2026, source: cathedral.ru).

## Savior on the Spilled Blood: the same 700 ₽, but for the mosaics
2b Griboedov Canal Embankment, Nevsky Prospekt metro, seven minutes from Kazan Cathedral. Ticket — 700 ₽, concession — 300 ₽, the same hours: 10:00–18:00, ticket desk until 17:30, closed on Wednesdays (checked 18.09.2026, source: cathedral.ru).
People go inside for the mosaics: the walls and vaults are entirely laid in smalt, there is almost no painting. The second thing is the canopy over the preserved stretch of pavement, the spot where Alexander II was fatally wounded. The cathedral is small, in July it gets crowded. Within the same fence there is a chapel-museum for 100 ₽ (checked 18.09.2026, source: cathedral.ru). The museum does not offer a climb up the bell tower.
## St Nicholas Naval Cathedral: the sailors' cathedral and a tour for 300 ₽
Nikolskaya Square by the Kryukov Canal, Sadovaya / Sennaya Ploshchad / Spasskaya metro, then ten minutes on foot. Entry is free.
The cathedral has two floors: the lower church is always open, and you are let upstairs on a tour — on Saturdays and Sundays at 12:30, recommended donation 300 ₽, booking via timepad, meeting point at the "Obraz" pilgrimage centre (checked 18.09.2026, source: nikolskiysobor.ru). Mid-18th-century baroque that was not rebuilt from scratch.
Liturgies daily at 06:40 and 09:40, evening service at 18:00 (checked 18.09.2026, source: nikolskiysobor.ru). It is best to check visiting times outside services on the day of your visit: the church's schedule can change on feast days and during services. Outside, the cathedral stands in the "seven bridges" spot — the shot is free and better than many paid viewpoints.
## Smolny Cathedral: a 50-metre climb for 300 ₽
1 Rastrelli Square. There is no metro nearby: from Chernyshevskaya it's about two kilometres — by bus, taxi or on foot through the Tauride Garden. It's worth going for the belfry: 50 metres, 278 steps, recommended donation 300 ₽, 150 ₽ for pensioners and schoolchildren, free for students and children under 7, no booking needed, open daily from 8:00 to 20:00 (checked 18.09.2026, source: smolnyspb.ru).
Compare with St Isaac's: 700 ₽ and 43 metres versus 300 ₽ and 50 metres. The view is different — the bend of the Neva and the monastery from above.
Inside the cathedral is white, almost without gold — Rastrelli conceived it as a light-filled space. Tours run at weekends; the ticket is bought separately — see the schedule and conditions on the cathedral's website (smolnyspb.ru). The church's schedule can change on feast days and during services, so it is best to check visiting times outside services on the day of your visit.
## Vladimir Cathedral: the cathedral the locals go to
20 Vladimirsky Prospekt (checked 18.09.2026, source: vladimirsobor.spb.ru), Vladimirskaya / Dostoevskaya metro — literally a step from the vestibule, there is no cathedral in the city closer to a metro. Entry is free.
Open from 8:00, on weekdays confession at 8:30 and liturgy at 9:00, on Sundays and feast days confession at 6:30 and 9:30, liturgies at 7:00 and 10:00, evening service daily at 18:00 (checked 18.09.2026, source: vladimirsobor.spb.ru). It is best to check visiting times outside services on the day of your visit: the church's schedule can change on feast days and during services.
An 18th-century parish church with a separate bell tower; no visitor climb is listed on the website. Here you can see what a non-touristy St Petersburg cathedral looks like on an ordinary day.
