Hallgrímskirkja is Iceland tallest and most iconic church, standing at 73 meters. Designed by state architect Guðjón Samúelsson in 1937, its distinctive expressionist architecture was inspired by basalt lava columns found in Icelandic nature. Construction took 41 years (1945-1986). The tower offers panoramic views of Reykjavík, surrounding mountains, and on clear days, Greenland. A statue of Leif Eriksson stands in front.
