The Collegiate (since 1992 the Cathedral Diocese of Zamość and Lubaczów) Church dedicated to the Resurrection and St. Thomas the Apostle was built at the turn of the sixteenth and seventeenth century in the style of the late renaissance. The temple had the same role to Zamosc and Zamoyski’s ordination then the Wawel Cathedral for Cracow and the Republic of Poland. The rich architectural decoration accompanied by an equally stunning interior - with the paintings by the great Italian master Jacob Tintoretto. In the crypts under the Church all the Ordinates were buried and it was made the Zamoyski - ancestral mausoleum of Zamoyski and it is opened to the public.

Next to the Cathedral there stands a tall Baroque bell tower, which overlooks on the city. In some part of the Cathedral’s, in the so-called Infułatka, there is a Sacral Museum created by the efforts of the last ordinate Jan Zamoyski.
