Church of St. Mary of the Angels, Vienna

Ornately decorated on its interior, the Capuchine Order has provided an impressive and interesting attraction for sightseers, but even more fascinating is the crypt located below the church. Here are the vaults of the Kaisergruft, or the imperial crypts, dating back to 1619 and founded by the Catholic Emperor Matthias. Buried here are 138 Habsburg tombs including the infamous Maria Theresa, her husband Franz Stephan, Franz Joseph, and Empress Zita. Although there is no gift/book shop, one can buy informative pamphlets and crypt guides/plans at either the church or at the crypt. The church is open to the public free of charge, however, the Kaisergruft has more limited hours and charges a fee for tours.
