In 1876, an unprecedented flood of the Guadiana River revealed previously unknown ruins: the Roman Villa of Montinho das Laranjeiras. Founded in the 1st century BC, it was inhabited continuously until the end of the Islamic period, when it was finally abandoned. Its privileged position allowed trade along the river as far as Mértola and ensured the continuity of Roman, Visigothic, and Islamic occupation.

If you visit this reservoir, be sure to visit the other dam, Odeleite, a few kilometers further north, which is almost even more beautiful. At both dams you will find hiking trails, peace and quiet, and sleepy villages.

The reservoir is really beautiful. But I haven't seen a full lake here for years. The drought here is getting worse every year

Cycling along the Guadiana River from Castro Marim it's a great experience. The road is not very busy. Mandatory visit.
