Description
Great Gransden Mill Road Post Mill is a post and open trestle mill built around 1612, making it the oldest remaining mill in England. The structure has two storeys and is covered with tarred weatherboards. On the second floor, there are two pairs of over-driven Burr stones. A sack hoist is operated by a wooden pulley located on the windshaft behind the tail wheel. The first floor features a flour dressing machine with the inscription 'IL 1774 RW'. The mill is currently undergoing restoration as of 1982.
