established in Friesland in 1680. On 9 November 1959 the mill was burnt down.
The present Aylvapoldermolen was built at Hallum
in 1846. It was known as the Vijfhuistermolen or the Hoekstermolen. The mill was restored in 1964 and again in 1971. On 4 May 1976 it was sold to Stichting De Fryske Mole (English: Frisian Mills Society). In 1989, the Stichting Aylvapoldermolen (English: Aylva polder mill society) was set up with the aim of rebuilding a windmill on the site of the lost mill. It was suggested in 1996 that the Vijfhuistermolen would be a suitable candidate as a replacement because the land it stood on was needed for the expansion of a business in Hallum. The mill was dismantled in 1999 and re-erected in Burgwerd on the site of the original Aylvapoldermolen. The official opening ceremony was performed on 3 June 2009 by Mrs Annemarie Jorritsma
, at that time the Minister van Economische Zaken. Mrs Jorritsma is the daughter of a miller. On 20 August 2009, the mill was struck by lightning
and set on fire. The fire brigade was able to confine the damage to the thatch on the cap. The mill is equipped with an automatic sprinkler system. The fire brigade used 135000 litres (29,695.8 imp gal) of water to extinguish the fire. About 6 square metres (64.6 sq ft) of thatch was destroyed.

Description
The Aylvapoldermolen is what the Dutch describe as an "achtkante grondzeiler". It is a smock mill without a stage, the sails reaching almost to the ground. The brick base is one storey high with a three storey smock on top. Both smock and cap are thatched. The four Patent sails, which have a span of 22 metre are carried on a cast iron windshaft. The windshaft also carries the brake wheel which has 57 cogs. This drives the wallower (32 cogs) at the top of the upright shaft. At the lower end of the upright shaft the crown wheel (53 cogs) drives the steelSteel
Steel is an alloy that consists mostly of iron and has a carbon content between 0.2% and 2.1% by weight, depending on the grade. Carbon is the most common alloying material for iron, but various other alloying elements are used, such as manganese, chromium, vanadium, and tungsten...
