St. Andrew's Church, Kraków

This guide to Saint Andrew's Church in Kraków opens in twelve forty-one, as Mongol horsemen sweep into the city and every wooden church begins to burn, except this one. It follows the fortress-like stone walls a nobleman named Sieciech built decades earlier, the archer loopholes still visible in the facade, and the Poor Clare nuns who took over the building in thirteen twenty under a vow of strict enclosure. Listen for the contrast between the plain Romanesque towers and the Baroque domes added centuries later.
