Andrzeja) in the Old Town district of Kraków, Poland located at Grodzka Street, is a historical Romanesque church built between 1079 and 1098 by a medieval Polish statesman Palatine Sieciech.

Along the lower part of the broader section of its façade are small openings that served as defensive windows at a time when the church was a place of refuge from military assaults.

The apse decorated with a modest arcade freeze and numerous details (including stairs and window frames) maintain the same character.

At that time, it was – quite rightly – called “the lower castle” to be distinguished from the nearby “upper” standing on top of the Wawel Hill.

Attention is drawn to the pulpit in the shape of a boat, and the musical choir with 18th-century organ in the chancel, decorated in the rococo manner.
