Archaeological investigations carried out on church sites often lead to the discovery of buried crypts, containing the remains of several deceased. The favorable conditions within the crypts have allowed fragments of their clothing to be preserved. In many cases, representatives of the priesthood in their sepulchral vestments were also buried in these crypts. Their garments were either made especially for the occasion or were composed of chasubles that had already been damaged and were no longer in use at the time of the funeral. This is the case with the two chasubles from Piaseczno, one found in the crypt and the other still hanging in a wardrobe at the back of the church.
