On the west side of Spišské Podhradie, you'll find still-active Spiš Chapter, a 13th-century Catholic complex encircled by a 16th-century wall. The pièce de résistance is St Martin's Cathedral (1273), towering above the community of quirky Gothic houses and containing some arresting 15th-century altars.
Buy tickets for the cathedral and pick up a guide from the (often-closed) information office at Spišská Kapitula 4. If you're travelling to Spiš Chapter by bus from Levoča, get off one stop (and 1km) before Spišské Podhradie, at Kapitula.
The Romanesque cathedral features twin towers and an ornate sanctuary; the altars are impressive tri-fold-painted sights. Spiš Chapter is part of the wider Spiš Castle & Levoča Unesco World Heritage site – locals call it the Slovak Vatican!
