In 2005, a farm dating from the end of the Middle Ages and the early Modern Period was excavated at Conchil-le-Temple (Pas-de-Calais), a small village in the Ponthieu region, 2,5 km from the north bank of the river Authie. The farm evolved through 3 main stages : phase 1 - a building resting on a row of supporting posts ; phase 2 - a rectangular timber framed construction of an estimated surface of 230 m2 flanked to the N-E by kitchens, and phase 3 - following a fire late 15th / early 16th century, a group of stone-built structures forming an L around a courtyard. A carefully prepared stone « mortar » was used in the foundations. The establishment was abandoned in the course of the 16th century. The impressive constructions of phases 2 and 3 are particularly well-finished. The nature of the metallic and ceramic finds attests a largely agriculture-orientated activity.
