This amazing Church is the one of the most beautiful buildings I've seen, inside and out. It is the main landmark in Reykjavik. The statue of explorer Leif Erikson (c.970 – c.1020) by Alexander Stirling Calder in front of the church predates its construction. It was a gift from the United States in honor of the 1930 Althing Millennial Festival, commemorating the 1000th anniversary of Iceland's parliament at Þingvellir in 930 AD. The church is named after the Icelandic poet and clergyman Hallgrímur Pétursson (1614–1674), author of the Passion Hymns. (with thanks to Wikipedia for filling in the details)
