Mühlenhof Breckerfeld, Open-air museum in Breckerfeld, Germany.

The Mühlenhof Breckerfeld is a freely accessible open-air museum on the northern edge of Breckerfeld, assembled from relocated historic farm buildings. Its centrepiece is a post mill built in 1846 in the Mark Brandenburg, fitted with two cog wheels, a sack hoist, a stone-lifting crane, two canvas sails and two slatted sails. Beside it stand a clay grain store from the Soest area, a bee house from Hünningen and a 1755 three-post farmhouse with baking oven from Heiden.

The open-air museum was created from 1996 by Dietmar and Helga Thorschmidt on the northern edge of Breckerfeld, with help from the town and volunteers. The post mill was built in 1846 in the Mark Brandenburg; the 1755 Dreiständerhaus with its baking oven came from Heiden, the clay grain store from the Soest area and the bee house from Hünningen. A forced auction was scheduled for 16 November 2018; in early 2022 Philippe Bremicker, Mirko Krüger and Jan Winterhoff bought the site and founded the Mühlenhof Breckerfeld e. V. to run it. The mill was restored in 2022; its sails had turned from 2010 to 2012 and then stood still.

The farmhouse is a Dreiständerhaus built in 1755 in Heiden, with its original baking oven. Its rooms are furnished with rural household objects from the 19th and early 20th centuries. The owner runs a bakery, a shop selling his own baked goods, cheese, meat and sausage, and a coffee room here to fund the free museum.

The site has a coffee shop and farm store selling freshly baked goods, cheese, meat, and local products made on the premises. Visitors can walk through the buildings at their own pace and watch demonstrations of traditional crafts that bring the rural setting to life.

The post mill's interior holds two cogwheels, a sack hoist and a stone-lifting crane, and its four sails mix two canvas and two slatted shutters. The mill turned from 2010 to 2012, then stood still; it was repaired in 2022 and its sails still await renewal.
