St. John's Cathedral (Katedra św. Jana)

This is the oldest church in Warsaw. Built in the 14th century as a Mazovian Gothic church, the Cathedral served as a coronation and burial site for Dukes of Masovia. After the resolution of the Constitution of May 3, 1791 King Stanisław August Poniatowski went to the Cathedral to repeat the Oath of the Constitution in front of the Altar. Also the Marshals of the Great Sejm were carried to the Cathedral on the shoulders of the enthusiastic deputies. The church was rebuilt several times, most notably in the 19th century. It was preserved until World War II as an example of English Gothic Revival. Leveled by the Germans during the Warsaw Rising 1944 it was rebuilt after the war. The exterior reconstruction is based on the 14th-century church's presumed appearance, not on its prewar appearance.
