Impressive Perlan is a stand out piece of architecture and modern construction in Iceland.

Perlan is one of Reykjavík's most striking buildings, and although it was opened to the public in 1991, it still impress guest from all over the world. 

Up on the fourth level there is a 360 degree viewing platform where you can get the best panoramic views of Reykjavík, and when the sun sets it's a spectacular spot for the Northern Lights.

You can also dine at the Perlan restaurant that slowly rotates so you get to see the whole city without even having to turn your head.
