Öland

Öland is a small island containing ruins, fortifications and 400 windmills. The biggest Iron-Age ring fort on the island, Gråborg - with a diameter of 200m (656ft) - is an incredible sight. Nearby, Eketorp has been partly reconstructed as a museum to show what a fortified medieval village must have looked like. Equally impressive are the ruins of Borgholm Castle, which was eventually burned and abandoned early in the 18th century. Also prominent are the lighthouses at the northern and southern tips of the island. Öland is reached from Kalmar via a 6000m (19,680ft) bridge, the longest in Europe. Öland is a popular place to celebrate Midsummer.
