Milecastle 29

Milecastle 29 is a Roman fortification in Northumberland consisting of a rectangular platform surrounded by deep trenches, situated near the B6318 Military Road. The structure preserves traces of its gateway openings and the interior layout that once housed a small garrison.

Built in the 2nd century AD under Emperor Hadrian's command, this milecastle formed part of a frontier defense network stretching across northern Britain. Soldiers stationed here monitored movement along the wall and provided accommodation for troops patrolling the region.

The site shows how Roman soldiers built their frontier installations through the placement of gates and drainage channels that visitors can still observe today. Walking through it reveals practical engineering choices made over 2,000 years ago.

The site is accessible via the Hadrian's Wall National Trail, which links various archaeological sites across the region. Sturdy footwear is recommended as the ground is uneven and the weather can change quickly.

The site retains visible remains of its surrounding ditch system, including a rarely preserved causeway crossing opposite the southern entrance. These features reveal how Romans engineered water-based defenses.
