Hyencourt-le-Grand is a former commune in the Somme department in Hauts-de-France in northern France. On 1 January 2017, it was merged into the new commune Hypercourt. Geography The commun is situated on the D164 road, some southeast of Amiens in the area known as the Santerre. History The first reference to the village of Hyencourt-le-Grand occurs during the Middle Ages when a château was built here. All that remains of the château is the chapel of Saint-Léger, rebuilt after the First World War and restored by local people in 2005. Buried beneath the village is a World War I military hospital. Occasional subsidence indicates its presence. Population See also Communes of the Somme department References Former communes of Somme (department) Populated places disestablished in 2017
