They were supported by the municipality through donations that were paid by the potential residents of these places, as well as by donations of townspeople, both rich and poor.

The preserved building of Jerusalem Hospital dates back to the 16th century founded on a rectangular, brick building, partly plastered, with two storeys. Gable roof covered with monk and nun tiles. The peaks of the double bent edges, topped with a frontage, decorated with plastered friezes framed with profiled cornices. Currently some restorative measures are taken by the German rescue association, which was established especially for this initiative. In the near future it is planned here to create a Museum of the City and the center of Polish-German cooperation.
