Sternberg Vault in Stupno, Noble family chapel in Stupno, Czech Republic.

The Sternberg Vault in Stupno is a free-standing Empire-style burial chapel built in 1808 or 1827, with a rectangular plan and a semicircular apse to the west. Its east front carries four Ionic columns with a triangular pediment topped by an iron cross, and a metal Sternberg coat of arms sits above the door. The yellow facade matches the colour of the family star; inside, a chapel with a circular plan holds a Neoclassical tomb, and the crypt below has a barrel vault with lunettes and grave shafts around its perimeter.

The Šternberk family acquired the Radnice estate in 1758, when Jan Nepomuk I of Šternberk bought it at auction. Kašpar Maria of Šternberg had the chapel built in 1808 or 1827 on a terrace visible from the staircase of Březina Castle. The first burial was Countess Aloisie in 1830; after a pause of more than a century, Zdeněk Sternberg and his wife Alžběta were interred in 2021.

The yellow facade matches the colour of the Sternberg eight-pointed star, shown in the metal coat of arms above the entrance. Inside the ground-floor chapel stands a Neoclassical tomb with the family coat of arms and a crucifix. At Kašpar Maria von Sternberg's grave lie broken geological hammers and a piece of fossil horsetail.

The chapel stands in the southwestern part of Stupno, a village that is part of the municipality of Břasy in the Rokycany district. A wide stone staircase leads up to the main entrance, followed by a path paved with granite slabs. The chapel became part of the cemetery only much later, so the graves around it are not contemporary with the building.

At Kašpar Maria von Sternberg's grave lie a broken geological hammer and a piece of fossilised horsetail, placed there in honour of the botanist, geologist and palaeontologist buried in the crypt. The last burials before a pause of more than a century were those of Zdeněk Sternberg and his wife Alžběta in 2021.
