Triel-sur-Seine is a French commune in the Yvelines department in the Île-de-France region, situated roughly 35 kilometres north-west of Paris and approximately 12 km from Saint-Germain-en-Laye, on the banks of the Seine. Its inhabitants are known as the Triellois.
A little history
According to Gautier de Coutances, the inhabitants of the banks of the Seine, Conflans, Andrésy, Triel, Vaux, Meulan, Mantes, la Roche-Guyon, and so on, are said to have been evangelised by Saint Nicaise, a disciple of Saint Denis. These facts would suggest that Triel, known as Triellum in Latin and then Trel in the Romance language, existed in high Antiquity. During the construction of the road and the station, a Merovingian cemetery was discovered, containing skeletons still adorned with their jewellery. A road, most likely of Gaulish origin, followed the bank of the Seine and linked the maritime provinces of the North-West to the capital of the Parisii.
