The Arctic Cathedral, formally known as Tromsdalen Church or Tromsøysund Church (Norwegian: Tromsdalen kirke or Tromsøysund kirke), is a church in the city of Tromsø in Troms county, Norway. The church is commonly nicknamed the Ishavskatedralen, literally "The Cathedral of the Arctic Sea" or "Arctic Cathedral". The church was built in 1965 in the Tromsdalen valley and it is a parish church and not, in fact, a cathedral as it is commonly called.
