This cathedral is an iconic part of the city skyline and the fourth biggest cathedral in the world.
Built in 1858 to be the main cathedral of the Russian Empire, no expenses were spared during the making of this impressive cathedral. The church is decorated with mosaics, semi-precious stones, paintings, and marbles.
Hear all about the history and architecture of St. Isaacs while enjoying the beautifully unique interior. Additionally, you can climb up about 300 steps to the observation ground and see one of the most spectacular views of the city.
We recommend to visit this church during the City Highlights Tour or Walking Tour.
