Grand-Arnsbourg fortified Chateau

Perched on a rocky ridge 110 m long and 6 to 38 m wide, it dates from the 11th century, although the site has been fortified since the 9th century. Destroyed by the troops of the Bishop of Metz, but rebuilt, it was gradually bought by the City of Strasbourg in 1480. Modernized in the 16th century to resist the emerging artillery, it was finally destroyed in 1676 by the troops of Joseph de Montclar.
