It is the largest castrum in Romania, occupying 37.5 hectares (93 acres) (750 x 500 m). It was the base of the legion Legio XIII Gemina transferred there by Trajan to the newly conquered province of Dacia at the end of the war in 106. In the era of Hadrian (117-138 AD) and of Antoninus Pius (138-161 AD) it was rebuilt in stone.

The city of Apulum grew up around the fortress, eventually becoming the capital of Roman Dacia.

The legion was relocated in 271 to Dacia Aureliana when the northern Dacia province was evacuated
