And the morbid vibes keep coming, because the Capuchin Monastery on Kapucínské Square is no place for the faint of heart. The exterior and ground floor are splendid, and offer no indication of what lies beneath. 

The building is in the baroque style, with an ornate rococo interior, including a memorable fresco and a preserved library with shelves of ancient volumes climbing to ornate ceilings. 

Go downstairs though and you’ll be confronted by an 18th-century crypt where members of the Capuchin order and other important figures of the time are lying around mummified like they’ve decided to take 200-year naps.
