Hamelin is a town on the river Weser in Lower Saxony, Germany. The town is famous for the folk tale of the Pied Piper of Hamelin , a medieval story that tells of a tragedy that befell the town in the 13th century. The old town was beautifully restored and has become a single splendid historical architectural landmark of international importance. Architecture enthusiasts call it a jewel of the Weser Renaissance.
