The Cathedral is the centre for Estonia’s Russian Orthodox community. A beautiful building with a prominent place on the Tallinn skyline and has been hotly debated for over a hundred years. The church was built in 1900 to symbolize the Russian Tsar’s power over the Estonians. Particularly interesting is the mosaic work and the colossal chandeliers inside the church as well as ancient Russian icons which are older than the cathedral itself. It is allowed to quietly walk into the church during the ongoing service.
