Castra Drobeta

The Drobeta (castra) was a fort built by Emperor Trajan in the province of Roman Dacia, in the present city Drobeta-Turnu Severin. It was built to protect the northern side of Trajan's Bridge across the Danube which was built quickly in preparation for Trajan's Second Dacian War in 103-105 AD. It was therefore in a key strategic location from where the imperial road north into Dacia started. Around it developed the Roman city of Drobeta. The fort has been extensively excavated and is visible today. It was the first stone fort built by Romans in Dacia and the only one that was used from the 2nd century until the beginning of the 7th century. The orientation of the fort is an exception to Roman military architecture as the Porta Praetoria gate is to the South, possibly because it defended the bridge.
