Lucheux (French pronunciation: [lyʃø]) is a commune in the Somme department in Hauts-de-France in northern France.

Lucheux is situated on the D5 road, some 18 miles (29 km) southwest of Arras, near the border with the neighbouring département of the Pas-de-Calais.

Laid to siege and taken again in 1595 during the same wars, this time by the Spanish under Hernando Teillo de Porto Carrer.

[5] The vestiges of the round towers are hidden on their exterior face, but the entrance is well restored.

The interior allows an understanding of the dimensions of the dwelling space available to the lord of the manor, with its walls and double bays of the Great Hall, below which one can see the moat and a preserved section of the keep or donjon.
