Mariendal parish was disjoined from that of St. Thomas' in 1905 when the owners of the Mariendal estate, Niels and Thora Josephsen, donated the building site and most of the funds needed for constructing the church and the parish hall. The street name Nitivej is a concentration of the couple's initials, "NJTJ". The Copenhagen Church Foundation erected a temporary church in cocolith, a mixture of fibers from coconut and plaster, which was moved to a new church project in 1908.
The barrel vaulted church room has a carved choir pulpit and wooden galleries in Art Nouveau style on three sides. In a crypt under the choir rest the remains of Niels and Thora Josephsen. Knud Larsen's original altarpiece has been integrated in a new decoration of the church's choir which was carried out in 1988 by artist Mogens Jørgensen.
The font by Siegfried Wagner is in granite with bronze-plate. The altar silver is endowed with jewels from Thora Josephsen's personal jewellery.
