St Mary's Church

St Mary's Church is the remains of a medieval brick building with visible foundations and walls displaying Gothic style features including two large western towers and a cruciform choir layout. The ruins stand in an archaeological park in the city center, offering a clear picture of the original structure's size and design.

The building was completed around 1314 and served as a royal chapel and seat of Norway's Chancellor until its destruction in 1523 during the Swedish independence wars. This destruction marked the end of its role as a center of state power.

The church held significant importance as a place where royalty and state officials conducted important matters. Walking through the ruins today, visitors can sense how deeply intertwined religious and political life were in medieval times.

The ruins are freely accessible in a public park in the city center and open to visitors year-round. Reading the information plaques on-site helps you understand which parts belonged to the original structure.

Excavations beneath the ruins uncovered an earlier wooden church dating to the 11th century that stood on this exact spot before the stone structure. This discovery shows how long this location served as a sacred place.
