Bieliński Palace, Otwock Wielki

Palace at Otwock Wielki or Otwock Grand Palace is otherwise known as the Jezierscy Family palace (Polish: Pałac Jezierskich) or Bielińscy Family palace (Polish: Pałac Bielińskich). It is a historic palatial residence located on an artificial island in an oxbow lake of the River Vistula in Otwock Wielki, in the gmina Karczew, powiat otwocki, masovian Voivodeship.

It is the former summer home of the Bielińscy family, old aristocracy (szlachta) from Ciechanów County in Mazovia, who maintained a close relationship with the Saxon court. But the family heirs squandered the family wealth in the 18th century, and the palace became in the end closely associated with the Jezierscy family szlachta, following the palace's acquisition by Jacek Jezierski. It remained in the hands of that family until the communist period of 1945 -1989. Recently, a court tort case has led to an administrative decision by the mazovian Voivode to return the property to the rightful Jezierski heirs. Nonetheless, the palace remains on public view, having been restored and opened to the public as Muzeum Wnętrz (Interiors Museum/Museum of Design in Otwock), a satellite branch of the National Museum, Warsaw.
