ROTUNDA OF ST. GEORGE, Sofia
Favorite thing: The red brick rotunda church of St. George is considered the oldest building in Sofia. It is situated behind the Sheraton Hotel, amid remains of the ancient town of Serdica. Three layers of frescoes have been discovered, the earliest dating back to the 10th century. Magnificent frescoes of 22 prophets over 2 metres tall crown the dome. At present the church is amuseum, but unfortunately has erratic opening times.
