[1] The gate, designed by Jean-Baptiste Veyren, was moved here from the Château d'Heilly in 1840.

[1] During World War I, the château was the Australian Headquarters under the command of General John Monash.

On 12 August 1918 Monash was knighted on the battlefield, a Knight Commander of the Order of the Bath, by His Majesty King George V, the first time a British monarch had honoured a commander in such a way in 200 years.

On the eve of ANZAC Day on 24 April 2016, the Governor General of Australia Sir Peter Cosgrove came to Bertangles[2] offering tribute to General Sir John Monash, with a tree-planting ceremony and the unveiling of a commemorative plaque.

It has been listed as an official historical monument by the French Ministry of Culture since 1982.
