Church of St. Adalbert, Kraków

The Church of St. Adalbert or the Church of St. Wojciech (Polish: Kościół św. Wojciecha), located on the intersection of the Main Market Square and Grodzka Street in Old Town, Kraków, is one of the oldest stone churches in Poland. Its almost 1000-year-old history goes back to the beginning of the Polish Romanesque architecture of the early Middle Ages. Throughout the early history of Kraków the Church of St. Wojciech was a place of worship first visited by merchants travelling from across Europe. It was a place where citizens and nobility would meet.

The Church was built in the 11th century and named after the martyred missionary Saint Adalbert (Polish: św. Wojciech) whose body was bought back for its weight in gold from the pagan Prussia and placed in Gniezno Cathedral by Boleslaus I of Poland. The Church of St. Adalbert stands at the south-eastern corner of the biggest medieval market square in Europe, demarcated in 1257. The place of worship preceded the Square by nearly a century. The interior of the church is cramped, relative to its larger exterior. The floor level is situated under the present level of the Square, which reflects the overlaying of the subsequent surfaces of the plaza with pavement originally adjusted to the two already existing churches (St. Wojciech/Adalbert and St. Mary's Basilica). The church was partially reconstructed in the Baroque style between 1611-1618.

According to the Archeological Museum of Kraków, the oldest relics reveal a wooden structure built at the end of the 10th century and followed by an original stone church constructed in the 11th century, as seen in the lower parts of the walls. These walls became a foundation for a new church built around the turn of the 11th and 12th centuries from smaller rectangular stones. Since the level of the plaza, overlaid with new pavement, rose between 2 and 2.6 meters, the walls of the church were raised up in the 17th century and then covered with stucco. The new entrance was built from the west side and the church was topped with the new Baroque dome. The restoration of the church conducted in the 19th century led to the discovery of its Romanesque past.
