Frederick's Church (Danish: Frederiks Kirke), popularly known as The Marble Church was designed by the architect Nicolai Eigtved in 1740 and was along with the rest of Frederiksstaden, a district of Copenhagen, intended to commemorate the 300 years jubilee of the first coronation of a member of the House of Oldenburg.

Frederick's Church has the largest church dome in Scandinavia with a span of 31m, though there are three larger domes elsewhere in Europe. The dome rests on 12 columns. The inspiration was probably St. Peter's Basilica in Rome.

The foundation stone was set by king Frederick V on October 31, 1749, but the construction was slowed by budget cuts and the death of Eigtved in 1754 and in 1770 the original plans for the church were discarded by Johann Friedrich Struensee. The church was left incomplete and, in spite of several initiatives to complete it, stood as a ruin for nearly 150 years.

The present version of the church was designed by Ferdinand Meldahl and financed by Carl Frederik Tietgen. It was opened August 19, 1894.
