The Muzeum Wnętrz w Otwocku Wielkim is a branch of the National Museum in Warsaw housed in an 18th-century Baroque palace situated on an island in the middle of a park-surrounded lake. Originally constructed as a summer residence for the Bieliński family, the palace features a central layout with a representative hall and preserved historical interiors. The collection focuses on Polish decorative arts, including furniture, clocks, and paintings from the 18th and 19th centuries. The site gained notoriety during the 20th century as a government guesthouse and an internment center for political figures, including Lech Wałęsa. Visitors can explore period rooms that demonstrate the aristocratic lifestyle and interior design aesthetic of the era. The property includes an extensive landscaped park and natural surroundings that reflect the original palace estate grounds.
