Téteghem is town situated in the North of France, 4 km away from the coastline and 3 km from Belgium. It’s located precisely in a “border region” on the maritime plain, on the south of the North sea. It’s an environment with variable sedimentary deposits like clay, peat and sand. Consequently conditions are good for potters’ installation. Recent archaeological surveys and digs yielded ceramic productions dating from the middle of the 12th century and an other from the second half of the 14th century. The techniques and decor includes Téteghem in homogeneous micro-regional ceramics that we can compare with others sites of the maritime coast. A particular production of brick objects is the most significant about our subjects. It’s formed of lids, spit-supporters, cups and double-bacs. They show an elaborated decor: line patterns incised, small triangles impressed by a knife, fingering, part coat with red slip and carved triangles patterns (so-called “keberschnidtt”). A synthesis of this type of objects is made in Netherlands (Dorgelo 1959 and more recently Heidinga & Smink 1982). There are other examples in North-West of Germany and on Belgium coasted. The distribution of these objects, already revealing the hanseatic trade road, have demonstrated a shared culture of the coasted people.
