Postmill Close, CR0 5DY
Open Days, see website
One of only four windmills open to the public in Greater London, Shirley Windmill is a Tower Mill, built in 1854 by Richard Alwen to replace an earlier (1808) timber post-mill on this site, lost by fire. It ceased working in about 1890, but most of the original machinery, including its two pairs of millstones, is still in place, and has recently been restored, so there is a lot to see.
