[1][2] The church was consecrated on 28 July 1957 and is dedicated to Hallgrímur Pétursson (1614–1674), who was the pastor of the local parish between 1651 and 1669.
[3] Icelandic State Architect Guðjón Samúelsson (1887–1950) was the first to draw a model of the church and it was according to his design that the foundations were cast.
In 1953, architects Sigurður Guðmundsson (1885-1958) and Eiríkur Einarsson (1907-1969) came together to design the current concrete church, with its brick interiors, copper roof and 20-metre-high (66 ft) tower.
Icelandic sculptor Gerður Helgadóttir (1928- 1975) designed the stained glass artwork of the church.
The frescoes around the altar are the work of Finnish artist Lennart Segerstråle (1892–1975).
