Reykjanesviti is Iceland's oldest lighthouse. It serves as a landfall light for Reykjavík and Keflavík. The tower is a 31 metres (102 ft) tall construction, situated on the southwestern edge of the Reykjanes peninsula. The original structure was built in 1878; just eight years later the building was destroyed by an earthquake. In 1929 the current Reykjanesviti lighthouse, a concrete construction yet with traditional looks, was illuminated. Its focal plane measures 73 metres above sea level.
