A Château Rich in History

The origins of the Asson estate date back to the 14th century, when it served as an important feudal seigneury. The present château, constructed around 1784 and carefully restored after the Wars of the Vendée between 1805 and 1807, stands on the site of an even earlier medieval fortress surrounded by moats and drawbridges.

Listed as a French Historic Monument since 1986, the protected designation includes not only the château itself but also its façades, roofs, chapel, historic watchtower, landscaped gardens, maze, wash house and the magnificent tree-lined avenues leading to the estate.
