The hilly riverside city of Plovdiv is considered to be one of Bulgaria’s most important cultural centers. Not only does it house old churches, mosques, and castles, but it also hosts various festivals catering to the fields of film, theater, music, and literature. Start exploring by traveling back in time at Ancient Plovdiv, a World Heritage Site comprised of the Plovdiv Roman Theater, the medieval gate of Hisar Kapia, the archaeological site of Nebet Tepe, and various Revival architectural landmarks. Fast forward to the present, revel in the creative district and local goods of Kapana. By nightfall, cap off your day by watching the Singing Fountains light show at the Tsar Simeon Garden.
