The Church of St. George Rotunda

As Sofia's oldest surviving building, the Church of St. George already deserves some of your attention. But, after seeing the red brick rotunda dating back to late antiquity and learning about the treasures that lay inside, you'll immediately want to know more. * Choose between an e-guide or a guided tour to learn more about the church's past, which goes all the way back to the Roman Emperor Galerius. The church is also part of a larger archaeological complex, so after you've seen the frescoes, make sure to step outside!
