Hallgrímskirkja is the 74-metre concrete church whose basalt-column tower is the best view over Reykjavik. Designed by state architect Gudjon Samuelsson in 1937 to evoke Iceland's geology, it took 41 years to build: the choir was consecrated in 1974 and the whole church only finished in 1986. It is the tallest church in Iceland and the visual anchor of the city, its stepped concrete flanks rising 74 m above Skolavorduholt hill like the basalt columns of Svartifoss stretched to cathedral scale. In front stands a statue of Leifur Eiriksson, gifted by the United States in 1930 to mark 1000 years of the Althing, and the church is named for Hallgrimur Petursson, the seventeenth-century pastor and poet whose Passiusalmar, the Passion Hymns of 1659, are still read aloud on Icelandic radio through Lent. People visit for the tower, where a lift climbs to a viewing platform with the whole city, the bay, Esja mountain and on clear days Snaefellsjokull spread out around you. Inside, the nave is deliberately austere: white walls, tall narrow windows and a 15 m Klais organ with 5,275 pipes installed in 1992, seating roughly 750 under a vault that gives the instrument an enormous reverberant tail. Free lunchtime organ recitals run in summer on Thursdays at noon. The address is Hallgrimstorg 1, at the top of the hill.
