At the southeastern corner of Kraków’s Main Market Square, the Church of St. Wojciech, also called St. Adalbert’s Church, is a small church with roots in the 11th century. Its Romanesque stonework sits alongside Baroque additions from the 17th century. Inside, look for fragments of Romanesque walls, a medieval crucifix on the triumphal beam and a painting of the Virgin Mary with Child. Glass panels reveal part of the older stone foundations, and a basement museum explores the church’s history. It is a compact stop between other sights on the square.
A church older than the square

The Church of St. Wojciech, known in English as St. Adalbert’s Church, stands at the southeastern edge of the Main Market Square. Its origins date to the 11th century, before the square took its present form. It is one of Poland’s oldest stone churches and an early example of Romanesque construction.
Tradition places St. Adalbert’s preaching at this site. The church’s position, lower than the surrounding square, also makes the area’s changing street levels visible: its floor sits about two metres below the current surface.
Romanesque walls and Baroque details

The building combines Romanesque remains with later changes. Renovations in the 17th century added Baroque elements, including a dome and a new western entrance. Outside, the stone façade and compact form make the church easy to distinguish from the larger buildings around the square.
Inside, look for fragments of Romanesque walls and a medieval crucifix on the triumphal beam. Baroque decoration includes a painting of the Virgin Mary with Child. The church is modest in size, so the visit is brief, but its architectural layers are close at hand.
What lies beneath the church
Glass panels in the floor reveal sections of the old stone foundation. They give a view of the structure below the present interior and connect the church’s lower floor to the history of the Main Market Square.
The Archaeological Museum of Kraków has a seasonal exhibition in the basement about the history of the square and the Church of St. Wojciech. It includes historical artifacts and reconstructed wooden elements associated with the church’s earlier structure. The exhibition runs from May to October, with free admission on Tuesdays. Check the museum’s current details before planning around a visit.
