Pyrenees Guide

Arreau occupies a strategic position at the meeting point of the Aure and Louron rivers. Half-way between the Atlantic and the Mediterranean, Arreau was probably a stopover on the ancient path between Iberia and Aquitaine. In the middle ages, it was a busy, powerful centre dominating four valleys. The wealth generated by the textile industries of the 16th century can still be seen today through numerous architectural marvels: the castle of Nestes.
