Milecastle 51, Roman fortification site on Hadrian's Wall, England
Milecastle 51 includes stone walls rising to 1.75 meters in height and covers a rectangular area measuring 19 meters by 15.5 meters.
The fortification was constructed around 122 CE as part of Emperor Hadrian's defensive barrier system stretching across northern Britain from coast to coast.
The structure represents the standard Roman military engineering practices, featuring a gateway design that controlled movement between the empire's northern frontier territories.
The site is accessible through the Hadrian's Wall Path, with several walking routes connecting to neighboring archaeological remains and observation points.
The milecastle retains visible sections of its original stonework, providing direct evidence of Roman construction methods used in frontier fortifications.
