Frederick's Church is a copper-green dome church. Because of the extensive use of marble produced in Denmark and Norway, the local people call it "marble church". The church has the largest dome in Scandinavia, with a diameter of 31 meters. The dome is placed among 12 cylinders. This design was probably inspired by St. Peter's Cathedral in Rome. The Marble Church was first built in 1779, but it was not completed and opened until 1894 due to financial problems. The church is separated from the Palace of Amerinburg. Visit the Palace of Amirinburg. You can see the church in the Palace Square. The appearance of the church was beautiful. We did not visit it.
