Closed since March 12 2012, the Museum has been the object of extension works since January 2011 aiming to double the surface by the construction of a new wing of 1000 meter squared. This subscription was in lieu to finance this enlargement of 3 million euros. This new museum, designated as « Louvre du Légionnaire » (The Louvre of the Legionnaire), was inaugurated on April 30 2013 following the arms ceremony marking the 150th Anniversary of the Battle of Camarón.
