Church of St. Michael the Archangel and St. Stanislaus Bishop and Martyr and Pauline Fathers Monastery, Skalka

Underneath is a crypt which holds the stone sarcophagi of the most important non-royal members of Polish citizenry throughout the ages.  Very exclusive group, about 12-15 sarcophagi with another two or three spots remaining.  So you are saying there is a chance!
