Church of St. Wojciech

This guide to the Church of St. Wojciech in Kraków opens in 997 on the Baltic coast, with the missionary bishop Adalbert killed by pagan Prussian warriors he had come to convert. It follows the legend back to this exact corner of the Main Square, where Adalbert is said to have preached in a small wooden church centuries before the square itself existed, and traces how that building became stone and, arguably, the city's oldest surviving church. Along the way is the tale of a Polish king who reportedly paid for Adalbert's body in gold, matching its own weight.
