The Open-Air Museum of Vistula Settlement in Wiączemin Polski

The Vistula Settlement Open-Air Museum, located in Wiączemin Polski, is a site dedicated to the culture of the Olędrzy settlers and their connections to Mennonitism and Lutheranism. The museum was established by the Masovian Museum in Płock, which purchased a 2.3-hectare plot in 2013 containing a church, a former school building, and a neglected Evangelical cemetery. The church, built in 1935 on a 3.5-meter-high mound to protect it from floods, initially served Evangelical congregations and was handed over to the Roman Catholic Church after 1945. Following a renovation completed in 2015, the church became a venue for cultural events. Two farmsteads were also relocated to the museum grounds: an Olęder-style Langhof, which combines living quarters and farm buildings under one roof, and a traditional Polish homestead. In 2017, the Masovian Museum secured funding of 7.5 million złoty, half of which came from the European Union and the other half from the Masovian Voivodeship local government. The museum opened on October 14, 2018, and in April 2022, it took under its care a Mennonite prayer house from Nowe Wymyślo. The museum showcases the rich history of Olęder settlement and their cultural heritage, serving as a valuable site for education and the preservation of tradition.
