History

The mill was originally built at Wormer, North Holland, Netherlands. During World War I, it was moved to Langweer, Friesland. It was dismantled in 1960 and re-erected at the Netherlands Open Air Museum, Arnhem, Gelderland in 1989. The mill was severely damaged in a snowstorm in 2000. It was restored in 2003.[1]

Description

The mill is what the Dutch describe as a Weidemolen (English: Meadow mill). It is a small hollow post mill on a roundhouse. The mill is winded by tail vane. The buck and roundhouse are covered in boards. The sails are Common sails. They have a span of 3.85 metres (12 ft 8 in). The sails are carried on a wooden windshaft. The windshaft carries the brake wheel which has 21 cogs. This drives the wallower (9 cogs) at the top of the upright shaft.[1] At the bottom of the upright shaft a centrifugal pump is driven.[2]

Public access

The mill can be viewed externally during museum opening hours.[1]
