Peter and Paul Fortress

About

Peter and Paul Fortress. You can go in for free, but to enter the church and exhibitions you need tickets. You can get a combo ticket for everything, or you can just enter the church. Other than the church, which is where the all of the Romanov Czars of Russia from Peter the Great (bar two or three) are buried, the other things on the island aren't terribly impressive, so it might be worth it to just see the church. Note that if you buy a combo ticket for everything, you still need to have a 'special ticket' for a lot of exhibitions within the fortress!
