The Cathedral was built on the hill just north of the area that is now the Old Town market square in Oslo (intersection of Bispegata –Oslo gate). For almost 500 years this was the most important church in the city. Besides being the bishop's seat and religious center, the cathedral was the coronation church, the royal wedding church and the royal burial chapel. The facility was in use as a church until about 1655. It fell into disrepair in the 17th century and is today a ruin situated in Minneparken.
