Hallgrímskirkja is a Lutheran parish church in Reykjavík, Iceland. At 73 metres high, it is the largest church in Iceland and among the tallest structures in Iceland. It has a stylised concrete exterior inspired by the distinctive basalt formations found throughout Iceland, such as the waterfall Svartifoss. This gives the building an appearance more akin to a space ship then a place of worship, and makes it a unique feature of Reykjavik’s skyline.
