Cathedral designed by Guðjón Samuel in 1937, who was often inspired in his endeavours by the fascinating shapes and forms created when lava cools into basalt rock.
Construction of the church began in 1945 and ended in 1986, with the tower completed long before the rest of the building. The crypt beneath the choir was consecrated in 1948, the steeple and wings completed in 1974 and the nave consecrated in 1986.
The church features, most notably, a gargantuan pipe organ designed and constructed by the German organ builder Johannes Klais of Bonn. Standing tall at an impressive 15m and weighing a remarkable 25 tons, this mechanical action organ is driven by four manuals and a pedal, 102 ranks, 72 stops and 5275 pipes, all designed to reproduce powerful notes capable of filling the huge and holy space with a range of tones - from the dulcet to the dramatic. Its construction was completed in December 1992 and has since been utilized in a variety of recordings, including some by Christopher Herric
