Oslo Cathedral stands in the heart of the city, and is surrounded by a little green area. The cathedral is also known as the Church of St. Saviour. It was founded after the Reformation, and was consecrated in 1697. Although many alterations have been made to the church over the years, the original Baroque altarpiece, pulpit and organ panels are intact. The stained glass windows are the work of Emanuel Vigeland. The cathedral is the venue for concerts of sacred music.
