The Church of Hallgrimur is the Evangelical Lutheran parish church of Reykjavik. Its distinct design has made it a landmark on the Reykjavik skyline but its history is also fascinating. The church is a national monument and dedicated to Hallgrimur Petursson (1614-1674), a religious poet who wrote the Passion Hymns. The church was designed by State Architect Guojonn Samuelsson; construction on the church began in 1945 and it was completed in 1986. The design incorporates Icelandic materials and traditional architectural styles.

The most interesting feature of the church is the 73 meter high steeple tower which was inspired by the basalt lava which flows from Icelandic volcanoes. The tower gradually climbs on either side instead of being straight up and down until it reaches a point. It is possible to take an elevator to the top of the tower for brilliant views.

The church has a famous organ inaugurated in 1992 and constructed in Germany. There are regular organ concerts held in the church as well as the Festival of Sacred Art and the International Organ Summer Festival. In front of the church stands a statue which was gifted to Reykjavik by the USA to celebrate the 1000^th anniversary of Icelandic government.
