Fodor's Expert Review Perlan

Glittering like the upper hemisphere of a giant disco ball, Perlan (the Pearl) is a grand construction of steel and mirrored glass. Perched atop Öskjuhlíð, the hill overlooking Reykjavík Airport, it's also one of the first landmarks to greet visitors when they arrive to the city. Supported by six massive water tanks and illuminated by 1,900 light bulbs, this impressive building opened in 1991 as a monument to Iceland's invaluable geothermal water supplies. It has since become a major tourist attraction, offering guests a host of amenities beneath its shiny surface, including souvenir shops, a café, an ice cave, a massive exhibition space, and a viewing platform with telescopes. Its crowning glory, though, is its revolving restaurant—it's pricey, but the panoramic views of the city and beyond are second to none.
