[1] The three-aisled hall church, which holds 1,200 people, has an 80-metre-high (260 ft) tower in the south-western part of the building.

Oscar's Church is located in the south-eastern part of Östermalm, where Storgatan and Narvavägen meet, near the Swedish History Museum.

The construction work was delayed several times because of problems with the foundation, non-deliveries and labour strikes, which is why the church was not consecrated until 1903.

In 1954–1956 further alterations were made to the interior, leading to changes in the altarpiece and the removal of some ornamental ceiling decorations.

[3][4] It was built in 1949 by the Danish firm Marcussen & Søn, to the wishes of Alf Linder, who was the church organist from 1943 until his death in 1983.
