The ruins of the Hinterhaus Castle originate from the 12th century. The castle dates back to the time of Kuenringers rule when it served as a strategic stronghold. From here they were able to rule the entire Wachau valley. Touring the ruins with the famous Red Gate gives visitors a good impression of what medieval defence methods were like. The ruins still offers visitors a fantastic view of the Danube river even today.
Olargues is a good example of a French medieval town and rated as one of the most beautiful villages in France. It was occupied by the Romans, the Vandals and the Visigoths. At the end of the 11th century the Jaur valley came under the authority of the Château of the Viscount of Minerve. The following centuries saw a succession of wars and epidemics, and it was not until the 18th century that Olargues became re-established. This was due to the prosperity of local agriculture and artisanal industry.
The Pont du Diable, 'Devil's Bridge', is said to date back to 1202 and is reputed to be the scene of transactions between the people of Olargues and the devil. The old village is clustered around the belltower, which was formerly the main tower of the castle (Romanesque construction). The old shops have marble frontages and overhanging upper storeys. A museum of popular traditions and art is to be found in the stairs of the Commanderie.
