The Roman town of Andelos is battered, but its remote and peaceful setting gives it a special romance. The town, which reached its peak between the 1st and 2nd centuries AD, is divided into three: the main town, a water reservoir about 300m away from the town, and the tumbledown walls of a dam about 3km from the main site.
In spring and autumn it's a lovely 7km round-trip walk to the dam walls along dusty lanes – take water and a picnic. There's also a small museum with some of the finds from the site just by the entrance. Andelos is close to the village of Mendigorría, which is a short way south of Puente la Reina.
