The Château de Meung stands right in the heart of this small Loire Valley town. Until the 18th century it served as the residence of the bishops of Orléans, and its mix of medieval fortifications and classical facades reflects centuries of renovation and expansion. The castle also has a darker side — its underground rooms were used as a prison, and you can still visit the cells. Literary fans know it as the place where Alexandre Dumas chose to open The Three Musketeers, with d'Artagnan arriving on his yellow horse. Just beside the château, the Collégiale Saint-Liphard is a fine Romanesque-Gothic church well worth a quick look.
Meung-sur-Loire itself is a quiet, pleasant stop along the river. A handful of streets with old stone buildings lead down to the Loire, and the town makes a good base for cycling the Loire à Vélo route. It lacks the tourist crowds of Amboise or Blois, which is part of the appeal — you get an authentic Loire Valley town without the coach tours. A short drive away, the soaring Basilica of Notre-Dame de Cléry holds the tomb of Louis XI.
