It's well smashed up, but it's scenically perched on the headland dividing the two bays, and has been a fort since prehistoric times. Much of the ruin is medieval, but it was in use into modern times, and shelled by German warships in 1914.
Scarborough Castle is a former medieval royal fortress situated on a rocky promontory overlooking the North Sea and Scarborough, North Yorkshire, England. The site of the castle, encompassing the Iron Age settlement, Roman signal station, an Anglo-Scandinavian settlement and chapel, the 12th-century enclosure castle and 18th-century battery, is a scheduled monument of national importance.
