Château des Ducs d’Alençon


The medieval Château des Ducs d’Alençon to open to the public at the end of 2019

Medieval fortress, alms house, prison, Gestapo headquarters, abandoned building … after a long and chequered history the grand medieval fortress of the Château des Ducs d’Alençon is now being transformed into an urban park!  Work on transforming this historic monument, bought by the City of Alençon in January 2018, has already begun and is due for completion in November 2019 when the grounds will be formally opened to the public.  We had a sneak preview of progress during a  guided visit on Saturday.

Two openings have been pierced in the wall overlooking the rue du Château and another in the curtain wall opposite, linking the rue du Château with the existing public garden to the rear of the Château des Ducs.


Other walls inside the château have been lowered, improving the view of the castle turrets.  A paved courtyard is being created which will also be used for shows, theatrical productions and so on.
