Nagytétény Castle, Baroque castle in southern Buda, Hungary

Nagytétény Castle is a yellow baroque palace with a dark tiled roof, a central section topped by a pale-green tower with a spire, and wings with rectangular windows and green shutters. It was designed by András Mayerhoffer and built between 1743 and 1751 for Baron József Rudnyánszky. Since 1949 it has housed the Museum of Applied Arts' furniture collection, with about 300 items shown in more than two dozen rooms.

A Gothic palace built in the 13th century for the Tétény family, related to the Árpád dynasty, stood here on Roman foundations. From 1541 to 1686 high-ranking Ottoman officers occupied it. After 1716 György Száraz began rebuilding, and András Mayerhoffer designed the Baroque palace erected between 1743 and 1751 for Baron József Rudnyánszky.

The museum opened here in 1949 as the furniture department of the Museum of Applied Arts, and the display fills more than two dozen rooms with about 300 pieces of Hungarian and foreign furniture, set among period carpets, stoves and ceramics. The Renaissance room served as the cover photo location for the band Locomotiv GT's first record, and scenes of the 1972 film Bob herceg were shot in the building.

The castle at 9–11 Kastélypark Street has been closed since 15 January 2018 for renovation works, with reopening announced for the end of March 2026. Check the museum's official site before travelling. The Kastélypark stop, opened in 2013 beside the park, serves the site.

The Renaissance room was used for the cover photo of Locomotiv GT's first album, and scenes from the 1972 film Bob herceg were shot in the palace. In 2019 the telenovela Bátrak földje used the building as the home of the Rokoczay family.
