Zaldapa (Zeldepa, Ancient Greek: Ζάλδαπα, Ζέλδεπα) was a large Late Roman fortified city in Scythia Minor/Moesia, located near today's Abrit, Bulgaria.

It was originally an ancient Thracian settlement from around the 8th century BC.[1] The site of over 35 hectares was protected from the East, North and Northwest by a deep valley.

Excavations have revealed the defensive walls, a Roman civic basilica, an early Christian basilica with two crypts and a huge water reservoir.[2] The walls had 32 bastions of various shapes and 3 main and 2 secondary gates. The double north gate was designed to enclose and trap attackers.

Zaldapa is included in the list of fortifications renovated during the reign of Emperor Justinian I the Great (527–565). It was also mentioned as the seat of a bishop.

In 2015, a Greek stone inscription has been discovered by the archaeologists excavating the ruins of a Christian bishop's basilica in the fortress of Zaldapa.[3]
