this early period comes mainly from fairly modest tombs such as those found in Niederanven. However, the tombs found in south-east Luxembourg at Grosbous, Flaxweiler and Altrier which date back to between 450 and 250 BC contained much richer finds. Judging from the objects discovered at Altrier, the tomb from about 450 BC must have been that of a high-ranking chieftain. It contained a bronze Etruscan stamnos, an iron sword, an ornate bronze and coral fibula (brooch) and a gold bracelet. The Grosbous tomb, part of a small cemetery, is particularly interesting as the corpse had been placed on a two-wheeled chariot providing indications of how the Celts constructed such vehicles. Principal Celtic sites The Celtic civilization was at its peak at around 300 BC, prior to the Roman conquest in 54 BC. Most of the evidence from that period has been discovered in tombs, many closely associated with Titelberg, a 50-ha site which reveals much about the dwellings and handicrafts of the period. Titelberg Titelberg is the site of a large Celtic settlement or oppidum in the extreme southwest of Luxembourg near Rodange and Differdange. Though it had been inhabited from about 300 BC, by the 1st century BC, the community had reached a high level of urbanization and was almost certainly the capital of the Treveri people. It was by far the largest of the Treveri settlements at the time, no doubt as a result of its proximity to two of the most important Celtic roads, one from the south connecting the Rhône to the Moselle valley and the north, the other leading to Reims and the west. Another attraction was the iron ore which could be mined in the immediate vicinity and was indeed increasingly smelted to produce knives, lances, swords and cooking utensils and equipment. Covering an area of some 50 ha, the oval-shaped Titelberg plateau rising 100 m above the river Chiers is approximately 1 km long (NW to SE) and 500 m wide. Evidence of the foundations of numerous dwellings, a public space for religious or political purposes, and the 9-m high ramparts which still stand at the SW entrance today, clearly demonstrate the importance of the oppidum which, until the Roman conquest, appears to have been the seat of the Treveri chieftains. One of the most important finds on Titelberg has been a huge number of Celtic coins which come from not only
