The Church Under the Street is a historical landmark in Trondheim, known for its unique exhibition on church ruins in the city. The exhibition focuses on a remarkable church find from the 11th century, which provides insight into Trondheim's role as an archbishopric in the Norse cultural area. Visitors can learn about the historical context surrounding the church and its significance for the development of religious practice in Trøndelag.
The architecture of the church is enigmatic and resembles private churches from the 10th century, which provides an interesting perspective on medieval life and culture. The church has been rebuilt several times in three, and there are also questions related to why the altar was preserved after the church's disappearance. The exhibition provides a deeper understanding of both the religious and cultural landscape of Trondheim through the ages.
