One of the attractions of Wejherowo is the Przebendowski and Keyserling Palaces, which were given their final shape in the mid-19th century. Currently, it represents a neo-Gothic style with distinct Renaissance elements. The building's structure, unusual for Pomeranian palaces, in terms of shape and appearance, is reminiscent of villas in southern Italy.
The palace now houses a museum that collects and promotes Kashubian and Pomeranian literary and musical heritage, as well as other cultural treasures associated with them. The museum has gathered over 100,000 exhibits, including historically valuable source materials that allow us to learn about the history of Wejherowo, including documents with the Wejher family's autographs. Exhibitions, literary competitions, conferences, meetings with creators and regional activists, concerts, and book promotions take place here.
The palace is a one-story building with an attic floor, high basements, three-winged, with an open courtyard facing north. The main wing is distinguished by central facades covered with stepped attics, similar-shaped gables, and attics crowning the side wings. On the garden side elevation, there is also a terrace and a small balcony on the short axis. The palace interiors have preserved the enfilade layout and original woodwork. The main halls are adorned with stucco ceilings and 19th-century wall paintings in the Pompeian style depicting Mediterranean landscapes. Original fireplaces have also been preserved in several rooms.
