Lancaster Roman Fort

Lancaster Roman Fort, also known as Wery Wall or Galacum, sits atop Castle Hill in Lancaster, England. First established around 71-80 AD as a turf-and-timber fort, it was rebuilt in stone around 102 AD and reconstructed at least six times over the centuries. Around 330-367 AD it was reduced to a Saxon Shore-type fort oriented against sea-borne raids from Ireland. The surviving Wery Wall fragment, a Grade II listed structure measuring 4m by 3m by 3m high, represents the core of a late Roman bastion. An adjacent bathhouse excavated in 1973 preserves heated rooms with hypocaust pillars.
