Perlan (english: Pearl) is a landmark building and one of the attractions in Reykjavík. Perlan is located on the hill Öskjuhlíð, where there had been hot water storage tanks for decades. Up on the fourth level is a 360° viewing platform, where you can get the best panoramic views of Reykjavík, and it is also a spectacular location for the northern lights. The metal framework of the building is pumped with hot water in the winter and cooler water in the summer, to help keep the exhibition space, the cafe and the restaurant at perfect temperature at all times.
