Originally two separate villages, Serres and Montguyard have been closely joined since the 12th or 13th century (since the Knights Templar) and now form one commune.
Serres is situated in the valley along the Dropt River and near the D25 departmental road.
Montguyard, a small, hillside village, has a Romanesque chapel, a spring and a Knights Templar’s Commandery of the Order of St Peter (private property).
The commune is in the canton of Eymet in southern Dordogne, bordering on the Lot et Garonne département.
It is reached either by :
• the D25 departmental road, or
• the Eymet-Serres communal road.
The commune has a surface area of 650 hectares and a population of 176.
