Shortly after leaving Chollerford you’ll come to the Chesters Fort Roman Site which is the most complete Roman cavalry fort in Britain. Chesters Fort (Cilurnum) was built in 123 AD just after the completion of the Wall and guarded a bridge, Chesters Bridge, which carried the Military Way Roman road, (not the more modern Military Road), behind the wall across the River North Tyne.
From Chesters Fort the path starts to rise and the countryside becomes moorland, rather than farmland. You’ll start to see a lot more of the Wall and parts of it run along the edge of crags, giving superb views over the open countryside to the north.
3 miles west of Chesters Fort lies Brocolitia, a Mithric Temple, which was probably built by soldiers based at the nearby Carrawburgh fort in about AD 200. The three altars found here were all dedicated by commanding officers of the unit stationed here, the First Cohort of Batavians from the Rhineland.
A further 5 miles brings you to Housesteads which is the extensive remains of an auxiliary fort on the Wall. The fort was built in stone around AD 124, soon after the construction of the wall began and it has had various names including Vercovicium, Borcovicus, Borcovicium, and Velurtion. The name of the 18th-century farmhouse of Housesteads gives it the modern name. There is an excellent museum run by The National Trust and English Heritage.
