Rogalin is primarily famous for its 18th-century baroque palace of the Raczyński family, and the adjacent Raczyński 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). The gallery was founded by Edward Aleksander Raczyński. Rogalin is also known for its putatively 1000-year-old oak trees on the flood plains of the Warta and the historical St. Marcellinus Church, whose design was inspired by the Roman temple Maison Carrée in Nîmes, France.
The last owner of the estate was Count Edward Bernard Raczyński, who in 1979–1986 was President of the Polish Republic in exile. His sarcophagus is deposited in the Raczyński Mausoleum, under the church in Rogalin. In his testament, Count Raczyński bequeathed his estate in Rogalin (including the family palace, gallery, library, and church) to the Polish people.
References:House of the Blackheads (Melngalvju nams) is a building situated in the old town of Riga. The original building was erected during the first third of the 14th century for the Brotherhood of Blackheads, a guild for unmarried German merchants in Riga. Major works were done in the years 1580 and 1886, adding most of the ornaments.
The structure was bombed to a ruin by the Germans June 28, 1941 and the remains demolished by the Soviets in 1948. The current reconstruction was erected from 1995 to 1999. Today the House of Blackheads serves as a museum and sometimes concert hall.
