To the right of the Cathedral is the stunning Archdiocese Museum (D-2, Pl. Katedralny 16), a do-it-yourself museum that throws rooms full of religious art at you and you’re left to decide for yourself what to make of it. Much of the art is recent - the work of local religious orders, but the largest room is filled with invaluable medieval works from around Poland. Art historians will no doubt find plenty of interest.

Admission 4/3zł.
