The exterior design of St. Mary’s Basilica is elegant yet simple. This entrance belies the opulence inside. Before going in, notice the abundant lancet windows set in red brick. This architecture style – called Brick Gothic or Polish Gothic – flourished in Kraków during the reign of Casimir III the Great from 1333 until 1370. Other 14th century landmarks in the city display similar characteristics. Examples include Town Hall Tower, St. Florian’s Gate, The Barbican, Wawel Cathedral and the lesser known Collegium Maius on the campus of Jagiellonian University. You should visit all of these during your exploration of Kraków.
