Barnet Gate Mill or Arkley Windmill is a grade II* listed tower mill at Barnet Gate in the London Borough of Barnet, originally in Hertfordshire. There is no public access.
Barnet Gate Mill was probably built between 1822 and 1840. A claim that it was built during the Napoleonic Wars (c.1800) has not been substantiated. Although steam had been added in 1895,[1] it was working by wind until 1916. The mill was restored in 1930.[2] A new cap, fantail and gallery around the cap being made. The work was done by Thomas Hunt, the Soham millwright. In a further restoration in 1985, the missing pair of sails was replaced.[1]
Barnet Gate Mill is a four-storey tower mill with an ogee cap which has a gallery. It has two Patent sails and two Common sails carried on a cast iron windshaft. The cap is winded by a fantail.[1]
The mill may have started life with two Common sails and two Spring sails carried on a wooden windshaft as the wooden clasp arm Brake Wheel has had to be fitted with packing pieces to enable it to fit the current windshaft, which being of iron is a smaller diameter than a wooden one would be. The Wallower is of cast iron, carried on a wooden upright shaft. This carries the Great Spur Wheel, which is of iron with wooden cogs and drove the two pairs of millstones underdrift. A third pair was added when steam power was installed. Only one pair of millstones remains today.[1]
