Archaeological excavations on the site of Muzillac Questannette revealed a funerary occupation dating from the second half of the Early Iron Age (Hallstatt D1-D2). It is characterized by a curvilinear enclosure ditch of nearly 50 m, defining an enclosed or semi-enclosed space within which a small monument is located, marked by a ditch forming a curvilinear plan. In its center is a burial represented by a quadrangular pit constructed with dry stones. Due to the acidity of the soil in the region, no bone remains were found. Nevertheless, the excavation of this burial site revealed a collection of 17 bracelets made of copper alloy. A vase, characteristic of funerary contexts in the region at the end of the early Iron Age, was also found in the upper fill of the structure. It is worth noting that another bronze bracelet, of much simpler design, was found in the eastern section of the clasp enclosure at the bottom of the structure. The study of the Muzillac Questannette burial site adds to our knowledge of burial practices in the second half of the First Iron Age in western France. It offers a unique example in the region, both in terms of architecture and the nature of the associated furnishings, and provides a relevant basis for comparison of burial practices and gestures during this period in the west of France. This example also gives us a glimpse of the socio-economic exchanges taking place at the time, demonstrating the rich sharing between the north-western Atlantic coast and the rest of the Hallstattian world.
