Eastern Gate of Philippopolis

The Eastern gate of Philippopolis is one of the three known entrances to the ancient Thracian city of Philippopolis [1]. The gate was built on the main road to Byzantium and the Bosphorus [1]. The Eastern gate was discovered in the 1970s [1]. After it was rebuilt in the 4th century, the Eastern gate of Philippopolis had one wide central entrance and two narrower side entrances [1]. Two watch towers were built on both sides of the gate for protection during attacks [1].
