St. Andrew's Church is the best example of the Romanesque style in Krakow. This church was founded in the 11th century by Sieciech, palatine of duke Wladyslaw Herman. The fortifying character of the church is visible, especially in the lower part of the building, where walls are incredible thick and there is hardly any windows. Two beautiful slim Romanesque towers are covered with Baroque helmets. The interior is mostly Baroque.
