Perlan — Wonders of Iceland Museum
Perlan ('The Pearl') is Reykjavík's natural history museum on Öskjuhlíð hill, housed in a distinctive glass dome atop six massive geothermal hot water tanks. The museum's star attraction is Iceland's only indoor ice cave, a 100-metre real ice tunnel carved into the building. Exhibitions cover glaciers, volcanoes, geology and Icelandic nature. The observation deck offers 360° views over Reykjavík, and the building itself is an architectural landmark.

Why Visit
Perlan ('The Pearl') is Reykjavík's natural history museum on Öskjuhlíð hill, housed in a distinctive glass dome atop six massive geothermal hot water tanks.
Did You Know?
The ice cave at Perlan is made from real glacier ice — but ironically, climate change is melting Iceland's real glaciers faster than they can be studied. Perlan's artificial cave may outlast the natural ones.
The Pearl on the Hill
Perlan was built to store hot water pumped from deep underground — but someone decided that if you're going to build six giant tanks on a hill, you should put a glass dome on top and make it beautiful.
