Rogalin [rɔˈɡalin] is a village in western Poland, situated on the Warta river. It lies approximately 7 kilometres (4 mi) east of the town of Mosina, and 19 km (12 mi) south of the city of Poznan.
Rogalin is primarily famous for its 18th-century baroque palace of the Raczynski family, and the adjacent Raczynski Art Gallery, housing a permanent exhibition of Polish and international paintings (including Paul Delaroche and Claude Monet and the famous Jan Matejko's large-scale painting Joanna d'Arc, see a fragment below). The gallery was started by Edward Aleksander Raczynski. Rogalin is also known for its putatively 1000-year-old oak trees (Polish: Deby Rogalinskie) on the banks of the Warta. Much of the surrounding area forms a protected area known as Rogalin Landscape Park.
The last owner of the estate was Count Edward Bernard Raczynski, who in 1979–1986 was President of the Polish Republic in exile. His coffin is deposited in the Raczynski Mausoleum, under the historical chapel in Rogalin. In his testament, Count Raczyński bequeathed his family palace in Rogalin and his library to the Polish people. wikipedia
