Marieux is situated on the D1 road, some 20 miles (32 km) north of Amiens.
The château was built in 1777 and is still owned and occupied by the same family today. Marieux is on the once strategically important and well-protected Roman road leading from Amiens to the English Channel and Britain.
During the First World War, it was British army headquarters for this part of the western front. On 25 October 1915, George V lunched here at the château with French Président Poincaré and the Chiefs-of-Staff of the French and British armies.
