Peace Mill, Protected windmill ruin in Klerken, Houthulst, Belgium

Peace Mill is a stone structure positioned on elevated ground along Molenweg road, featuring an observation platform accessible at the upper level. The building provides views across the surrounding landscape and serves as a focal point in the Houthulst region.

A wooden post mill for oil was built here under a patent of 7 June 1766; from 1 August 1791 it also milled grain. In 1879 Louis Vandenbussche replaced it with a brick stellingmolen, adding a steam engine in 1880. The mill burned in 1917 after a shell hit and was never restored; it was protected as a monument on 1 April 1999.

The mill's official name, "Vredesmolen" (Peace Mill), dates from 1 April 1999, the same day it became a protected monument. The name was chosen when the village council's rescue campaign, which gathered nearly 650 signatures in a village of 535 houses, led to the ruin being kept as a war memorial.

The brick tower stands on the highest point of Klerken, 43 metres above sea level, beside a lower brick outbuilding with a grey roof. A grey metal staircase with railings climbs the outside to a circular platform at the top; a steep spiral staircase of perforated metal grating winds up inside. The entrance to the collapsed wartime tunnel is still visible in the outbuilding.

The Germans left the mill on the night of 28 September 1918 through a tunnel dug during the war, emerging in lower meadowland; its entrance is still visible in the outbuilding, though the passage itself has since collapsed. The mill was renamed "Vredesmolen" (Peace Mill) on 1 April 1999, the same day it became a protected monument.
