Kastelo de Letenye, Noble residence in Letenye, Hungary.

Kastelo de Letenye is a noble residence in southern Hungary featuring symmetrical facades, tall windows, and a central entrance framed by columns. The building combines classical proportions with functional rooms designed for residential use.

The Szapáry family built the Baroque castle between 1758 and 1768, and it was rebuilt in Neoclassical form between 1821 and 1825. Around 1830 it passed by marriage to the Andrássy family, and Count Károly Andrássy, a parliamentary deputy, had it altered. Its last resident, the Swedish-born Countess Stella Kuylenstierna, left with her family in 1944.

The castle has housed a cultural centre since 31 December 1951, with a three-room museum on the ground floor and a cinema upstairs. In the park stands a twelve-sided library built by Imre Makovecz and a Kossuth memorial erected in 1894.

The castle stands in the centre of Letenye, in a park now covering 5.6 hectares. Since 31 December 1951 it has served as a cultural centre: a three-room museum occupies the ground floor and a cinema the upper floor. The walls are crumbling and water has seeped in, so parts of the building show decay.

The castle's last resident was Andrássy Imréné, born Swedish aristocrat Stella Kuylenstierna, who left with her family in 1944 as German and Russian troops advanced. She later recalled the thirty-room white castle standing in a huge park where flowers bloomed everywhere.
