Walls Castle, Roman Bath House, Ravenglass

Ravenglass Roman Bath House known as Walls Castle in the Lake District National Park, West Cumbria.
This bath house, established in AD 130, stands next to the site of the large Roman fort, Glannoventa which was the most southerly point of the Cumbrian coastal defence system and is the western extremity of the Roman Frontier World Heritage Site. There are no longer any signs of the fort, but the bath house is one of the largest surviving Roman structures in England, with walls almost 4 metres high. At least two rooms contained under-floor heating systems. The walls are of sandstone bonded with mortar and rendered internally with pink cement. The bath house would have been used both by Roman soldiers and civilians who lived in the nearby settlement.
