The Church of Our Saviour (Danish: Vor Frelsers Kirke) is a baroque church in Copenhagen, Denmark, most famous for its corkscrew spire with an external winding staircase that can be climbed to the top, offering extensive views over central Copenhagen. It is also noted for its carillon, which is the largest in northern Europe and plays melodies every hour from 8 am to midnight.
