The Imperial Crypt, also called the Capuchin Crypt (Kapuzinergruft), is a burial chamber beneath the Capuchin Church and monastery in Vienna, Austria. It was founded in 1618 and dedicated in 1632, and located on the Neuer Markt square of the Innere Stadt, near the Hofburg Palace. Since 1633, the Imperial Crypt serves as the principal place of entombment for the members of the House of Habsburg. The bones of 145 Habsburg royalty, plus urns containing the hearts or cremated remains of four others, are here, including 12 emperors and 18 empresses. The visible 107 metal sarcophagi and five heart urns range in style from puritan plain to exuberant rococo. Some of the dozen resident Capuchin friars continue their customary role as the guardians and caretakers of the crypt, along with their other pastoral work in Vienna. The most recent entombment was in 2023.
