Château Bisqueytan is a medieval fortress perched on a rocky outcrop above the Bisqueytan stream, its triangular form following the natural contours of the limestone plateau. Originally fortified in the 12th century with a chapel and donjon, the castle developed substantially during the 15th and 16th centuries under new ownership. The compound features distinctive machicolated walls and parapets encircling a lower courtyard, along with a notable colombier (dovecote) topped by a pepper-pot roof. Notably owned by the philosopher Montesquieu in the 18th century, both the château walls and dovecote are designated as historical monuments, preserving centuries of Aquitaine's medieval heritage.
