Named after 17th-century poet and cleric Hallgrimur Petursson, this isn't a Lutheran cathedral but a church - Iceland's largest, at 244 feet tall, and perhaps the capital's most It took 41 years to build, inaugurated in 1986, and its design said to evoke the basalt lava flows of Iceland’s rugged natural landscape. There's also an observation deck (reachable by elevator) to get a bird's-eye view over Reykjavík and the surrounding mountains.

It's one of Tripatini member Shiv's 7 Gems among Europe's Lesser Known Cathedrals and Churches.
