St. Peter's Church, Halden

The St. Peter's Church (Norwegian: St. Peter kirke) is a religious building of the Catholic Church that serves as the parish church in Halden, a city and municipality in the province of Østfold, Norway. It was inaugurated on October 10, 1877.

The church was designed by Dutch architect Pierre Cuypers. He had originally designed the church for a population of about 10,000 people, corresponding to the population of the Halden for the time. Catholics in the city amounted to about 20 people and plans were modified to build a 1/3 structure originally projected.

The church has neo-Gothic elements and was built in red brick.
