About

The castra of Poiana was a fort in the Roman province of Dacia near the present town of Poiana (previously Flamanda). It was built in the 2nd century AD and abandoned in the next century. It was a part of the Limes Transalutanus frontier system and situated at the southern end next to the Danube (and a presumed crossing point).
