Britain's oldest brick tower windmill which sits in the middle of a housing estate is still spinning over 250 years after it was built.br br Located in Holgate, York, Holgate Windmill has been working since 1770 after being built by George Waud, from Selby, North Yorks., after he bought the land on December 27 1768.br br The mill - which grinds corn to make flour - was built in open countryside looking over the hamlet of Holgate and was one of many mills in the Yorkshire region.br br The 90-foot-tall mill now sits on a roundabout in the middle of a housing estate which was built in the 1940s and 50s post World War Two.
