Yarm Castle in Stockton-on-Tees, England

Yarm Castle was built from grey stone in the 1880's by a local David Doughty who once lived in the adjoining house, many years later his son added to it by building Yarm town hall. It has turrets, ramparts and coloured glazed windows which were once illuminated by gas light. Don't go expecting drawbridges and moats and you might have to search a bit to find what is probably best described as a folly.
