Palatinal Crypt, Royal burial crypt beneath Hungarian National Gallery in Budapest, Hungary.

The Palatinal Crypt is a royal burial chamber located beneath the Hungarian National Gallery, filled with marble sculptures and bronze statues positioned along its walls. These artworks feature religious and political symbols, including a double life-sized statue depicting Palatine Joseph kneeling.

The crypt began as the underground vault of the Baroque Saint Sigismund church, consecrated in 1769. After the deaths of his infant daughter Elisabeth Karoline in 1820 and his son Alexander Leopold in 1837, Palatine Joseph had it converted into a family mausoleum by architect Franz Hüppmann, completed in March 1838. The last Habsburg burial was Archduchess Klotild in 1927; in 1973 robbers desecrated the sarcophagi, and the crypt reopened in 1987.

The crypt is entered from a gallery hall, and its three vaults hold 12 sarcophagi. György Zala carved the kneeling Palatine Joseph above the Crown of Saint Stephen; Alajos Stróbl modelled the praying child Elisabeth Clementine and the young Ladislaus Philip after death masks. Mass was permitted here by the Archdiocese of Esztergom from 23 April 1838.

The crypt is reached from inside the Hungarian National Gallery, through one of its exhibition rooms, so gallery admission applies. Visits are possible only on guided walks, not independently. The entrance was walled up in 1973 and the crypt was restored between 1985 and 1987, reopening on 3 October 1987.

The crypt holds 12 sarcophagi, not sixteen graves. In 1973 robbers broke in and threw the corpses from their coffins; archaeologist László Zolnay found Palatine Joseph's head severed from his body and placed it on his son Stephen's tomb lid.
