Post mill in Drewnica, Post mill in Drewnica, Nowy Dwór Gdański County, Poland

The post mill in Drewnica is a wooden post mill (koźlak) built in 1718, standing on a brick base and made entirely of timber. Its frame walls are clad vertically in boards, and the rectangular body is covered by a shingled roof shaped like an upturned boat, with an overhang sheltering a small gallery and tall steps up to the entrance door. Inside, the milling mechanisms and several pieces of old equipment survive.

This mill was built in 1718 by Dutch Mennonite settlers who brought their milling expertise to the Vistula Delta region. It served as a grain processing center for local farming communities for many decades.

This mill reflects how farming communities in the Żuławy region relied on wind power to process grain and sustain their livelihoods. The structure shows how settlers adapted their building traditions to this flat, windy landscape.

The mill sits in Drewnica near the address Wiślana 117A and is easy to spot with its brick foundation and wooden structure. The surrounding area is flat and open, making the location straightforward to reach and navigate.

Of roughly one hundred grain windmills still standing in the Żuławy region in 1945, only two survive today: this wooden post mill in Drewnica and a 19th-century brick-and-timber smock mill in Palczewo. The Drewnica mill is the sole surviving post mill of its kind in the region.
