Château d'Ajat, constructed atop the foundations of a 13th-century castle administered by the Templiers, evolved through architectural additions spanning the 14th to 18th centuries. Located 29 km east of Périgueux in Dordogne, the estate belonged to the Hautefort family branch and features two main sections connected by a two-story gallery that encloses a western courtyard. Machicolations and walkways adorn the facades, reflecting medieval fortification techniques. Listed as a historic monument since 1925, the privately-owned residence occasionally opens during summer months and for Heritage Days, offering glimpses into its layered medieval and Renaissance history.
