Milecastle 22

Milecastle 22 is a rectangular stone structure that formed part of Rome's frontier defenses along Hadrian's Wall and stands exposed on the Northumberland landscape. The ruins display substantial foundation walls that once enclosed this small military garrison.

The fortress was built around 122 CE under Emperor Hadrian and served border defense for over 250 years. It formed one link in an extensive system of military posts extending across the region.

The milecastle served as a checkpoint where Roman soldiers monitored travelers and trade goods moving across the northern frontier. Soldiers stationed here managed daily traffic control and border security in this remote location.

The ruins sit along the Hadrian's Wall Path hiking trail, where visitors can explore multiple Roman sites in sequence. Access is open and free, but the terrain is exposed and windy, so prepare with appropriate clothing.

Archaeological digs uncovered remnants of a stone oven and residential buildings, showing that soldiers were stationed here for sustained periods. These findings reveal how daily routines operated within the small garrison.
