Vézac is a commune in the Dordogne department in Aquitaine in southwestern France.
The main attraction of Vézac is the garden surrounding the Château de Marqueyssac —classified as a remarkable garden by the French Ministry of Culture—which was built in the 17th century by Bertrand Vernet, counsellor to the king. The original garden was created by a pupil of André Le Nôtre, and featured gardens, terraces, and a kitchen garden surrounding the chateau. A grand promenade one hundred metres long was added at the end of the 18th century. Beginning in 1866, the new owner, Julien de Cerval, who was inspired by Italian gardens, built rustic structures, redesigned the parterres, laid out five kilometres of walks, and planted pines and cypress trees.
