Thrigby Post Mill Thrigby · Norfolk · England

Thrigby Post Mill stands on the site of an earlier post mill associated with the Thrigby estate. The original mill was built in about the 1790s by Robert Woolmer, owner of nearby Thrigby Hall, to grind wheat produced on the estate. It stood south of Mill Road, east of Thrigby, and was marked on Faden's map of Norfolk in 1797.

The original post mill had the characteristic arrangement of a timber buck carried on a central post, allowing the whole body of the mill to be turned into the wind. It stood over a brick roundhouse, which sheltered the trestle and provided covered storage. The mill had four common sails. Early nineteenth-century notices record the windmill with a dwelling house, stable, granary, other buildings, a garden and about an acre of arable land at Thrigby, showing the mill as part of a small working milling holding.

The last miller was Alfred Hood, who also farmed locally. He worked the mill until 1889. In 1892 the timber mill body was found to be affected by death-watch beetle and was dismantled, leaving only the brick roundhouse. The site remained a visible mill survival but no longer a complete windmill.

In 1981 the mill was bought by Nick Prior, who began restoration. The roundhouse was repaired and the mill rebuilt on the earlier site. The present post mill is therefore a reconstruction on a documented historic mill site, preserving the form and setting of one of Norfolk's small number of post-mill survivals.
