[4] The road was vital in Trajan's Dacian Wars against the Thracian tribes north of the Danube, and later became more important as a main artery of the province.

In 254 another cohort was stationed here by emperor Gallienus and began building a new fort wall which continued till at least 282 under Claudius Gothicus, Aurelian and Probus.

The rebuilt fort from 254 AD was placed inside the original walls and conformed to later Roman norms with many bastions for better defence.

Recently a large Roman road station (mansio) near the fort has been excavated which covers an area of 500 sq.m with walls up to 2 m high.

[10] It is described as a luxury complex resembling a modern-day spa resort and dating from 100 AD; it has also been described as a praetorium because it was a meeting place for VIP visitors.
