General Jan Henryk Dąbrowski Palace in Winna Góra is an 18th-century historic residence, built between 1760 and 1770 on the initiative of Poznań Bishop Teodor Kazimierz Czartoryski. Originally Baroque in style, the palace was surrounded by a French-style garden and orchards, but in 1796 it was confiscated by the Prussian authorities. In 1807, Napoleon Bonaparte gifted it to General Jan Henryk Dąbrowski, who transformed it into a national sanctuary, the Temple of Victory, where he collected memorabilia related to Polish history and the struggles of the legions. After Napoleon's fall, the palace became an important center of Polish national thought, hosting prominent figures such as Julian Ursyn Niemcewicz and Henryk Sienkiewicz.
After Dąbrowski's death, his estate passed into the hands of the Mańkowski family, who between 1910 and 1911 erected a new palace designed by Stanisław Borecki. This modern building combined elements of a traditional manor house with innovative architectural solutions, such as a large portico and stylish interiors with modern amenities. After World War II, the palace was nationalized, and its collections were destroyed or scattered. In 1963, the building was handed over to the Institute of Plant Protection, and in 1987, the "General J.H. Dąbrowski Memorial Room" was established there.
Since 2003, the palace has transitioned from private ownership to cultural institutions and is now an independent cultural institution of the Greater Poland Voivodeship. In 2021, it took on the role of a history interpretation center, focusing on the figure of Dąbrowski and organic work, organizing cultural events, and collaborating with local organizations. Dąbrowski Palace aims to build regional awareness by exploring how Polish history can be used to understand contemporary issues. It is also worth noting that the palace is a unique example of architecture and history, commemorating significant events in Polish history and the figures who shaped national identity.
