The tombstone of Jan Magnus Tęczyński, which can be seen today in the Tenczynek's church floor, is the second in turn and was funded in 1894 by countess Katarzyna Potocka. It commemorates the last representative of the Tęczyński family, the owner of the property, protector of Piotr Kochanowski and the funder of two monasteries.
