Schwarzenberg Vault in Orlík nad Vltavou, Neo-Gothic family tomb in Orlík nad Vltavou, Czech Republic

The Schwarzenberg Vault is a Neo-Gothic tomb built in 1861–1864 to a design by princely engineer Antonín Šiman. It stands on a regular cross plan with two main floors, side staircases ending at the upper floor, an attic level, and a narrow bell turret rising from the centre of the roof. The southwest entrance portal has massive carved doors flanked by panels with Latin Bible quotations.

Karel I Philipp of Schwarzenberg proposed a new vault for the family's Orlík branch in his will, but choosing a site took years; extending existing tombs at Mirotice, Stražiště or Svatý Jan was considered first. Prince Antonín Šiman designed the building in 1860, it was erected in 1861–1864 and consecrated on 15 October 1864 by Archbishop Bedřich of Schwarzenberg. Karel I's remains were moved here from Třeboně on 3 February 1865.

The entrance displays biblical inscriptions and intricate wood carvings that reflect how the family expressed their faith and status through the space. These decorative elements show the craftsmanship valued during the era when the structure was completed.

The tomb is located approximately 1.5 kilometers northwest of Orlík Castle and requires advance arrangements to visit the interior. It is advisable to contact the castle administration to arrange a visit, as access is restricted.

The vault holds 24 members of the Schwarzenberg secundogeniture, including Karel I. Filip, his wife Marie Anna and son Karel II, whose remains were moved here from Třeboně in 1865. The last interment was politician Karel VII./I. Schwarzenberg in 2023. During communism only Arnošt Schwarzenberg was buried here.
