The Hallgrímskirkja - church of Hallgrímur is a Lutheran (Church of Iceland) parish church in Reykjavík, Iceland. At 74.5 metres (244 ft), it is the largest church in Iceland and the sixth tallest architectural structure in Iceland after Longwave radio mast Hellissandur, the radio masts of US Navy at Grindavík, Eiðar longwave transmitter and Smáratorg tower.The church is named after the Icelandic poet and clergyman Hallgrímur Pétursson (1614 to 1674), author of the Passion Hymns.
I loved it very much, very different from the churches you see around Europe. The inside is very modest, no paintings at all. The organ though is very impressive. The statue outside of it is a present from the United States and it represents Leif the Lucky, discoverer of North America. For 750 krona you can go up in the tower and see the entire city, very nice view. Kids go free :)
