St. Isaac's is also the third largest church in the world, after St. Peter's in Rome and St. Paul's in London. The gilded dome is a landmark that can be seen all over the city. The outside is quite sober looking, with dark columns on each side. The bronze doors reminded me of the doors at the Duomo in Florence. Inside there are paintings and mosaics everywhere.
