Brunszvik Mansion, Classical mansion in Martonvásár, Hungary.

Brunszvik Mansion is a residential building featuring neo-Gothic Baroque design with three-arched windows and a distinctive tower rising from its structure. The main wing contains eleven rooms and now serves as both a museum and cultural space.

Antal Brunszvik, who received the county title and the Martonvásár estate from Maria Theresa, died in 1783 and his lands were divided among his children; Martonvásár went to Antal's line, and in 1785 a single-storey Baroque manor house of eleven rooms was built there while the Beniczky family still held the land. Ferenc Brunszvik added an upper floor in the 1820s in Neoclassical style, and his son Géza rebuilt the mansion in Neo-Gothic style between 1872 and 1875. In 1897 the brewer Antal Dreher bought it and kept it until 1945; since 1953 it has belonged to the Hungarian Academy of Sciences.

The Brunszvik family welcomed Beethoven as a guest multiple times, and the house preserves memories of their artistic connection. Visitors can explore traces of this relationship and the cultural life that flourished here during the 1800s.

The 70-hectare English park lies north of the mansion, with the Szent László stream dammed to form a small island reached by paths; the Beethoven statue stands on that island. The park has been a nature reserve since 1953 and is maintained by the MTA Agricultural Research Institute, so expect working farmland alongside the walks.

The 70-hectare English park was laid out for Ferenc Brunszvik by designer Christian Heinrich Nebbien, who dammed the Szent László stream to form its island. Pásztor János's Beethoven statue was placed there for the centenary of the composer's death. The park has been a nature reserve since 1953 and is maintained by the MTA Agricultural Research Institute.
