The first occupations... Traces of prehistoric occupation were found on various sites of the commune. Similarly, the dolmen of Peyrelongue denotes a human presence dating from the Neolithic. The first writings of the parish only appeared in the fourteenth century. Yet the church is dated from the thirteenth century by some characteristic architectural elements.
The castles... Two small châtellenies are mentioned one at the place called La Gardelle and the other of Castellot. Only the two "English" towers remain in the hamlet of La Gardelle. The Hundred Years War was the most tragic for the parish because of the presence of the two castles from which the bands of robbers shone, plundering and massacring for the English or the French according to Their interests. The intervention of the Sénéchal du Périgord with the support of the Sarladais ended it and the two castles were razed. In 1453, there remains only one ruined parish.
Several names... Over the centuries, the commune often changed its name. In the 17th century, it was called "Saint Laurent de Castelnaud", a name dating from the period of feudalism relative to the seigniory of Castelnaud. By decree of November 20, 1903, made on the proposal of the Minister of the Interior and Religious, it takes the name of "Saint Laurent la Vallée". La Vallée Creek is a vauclusian type resurgence. According to legend, Saint Laurent refused to give the treasures of the church during the persecutions of the third century.
Emerging from the depths of the valleys, you can see on the plateaus wide viewpoints from one valley to the other featuring a bocage-like landscape in the presence of farms and hamlets surrounded by meadows and cultivated fields. In the midst of this undulating landscape, the richness of this commune resides in this balance between the wild aspect of woodlands, the agricultural openings that are living and moving places, and the reception of an increasingly widespread green tourism that Animates the hamlets.
