Visby's spectacular town walls are about 3.5 kilometers long and were built of limestone in the latter part of the 13th century. Dotting the walls are 44 towers standing 15-20 meters high.
Near the north-end stands the Maiden's Tower (Jungfrutornet), where legend has it that the daughter of a Visby goldsmith was walled up alive for betraying the town to the Danes out of love for the Danish King, Valdemar Atterdag.
From here, the walls run east to the line of cliffs, turn south at the town's main gate (Norderport), follow the edge of the cliffs to Söderport (South Gate), and finally veer west to end at the ruins of Visborg Castle overlooking the harbor.
