Luy

Etymology

Its name is probably related with the Basque Lohi “mud”. It is documented in the old texts in the forms Him (1170), lo Hui (1286)… According to Pierre de Marca, the cartulaire of Lescar (1101) mentioned it in the Latin form Lunius .

Geography

Luy is consisted of the junction of two close rivers, the Luy de Béarn (77 km) in the south and the Luy de France (principal course) a little more in north. Both take their source in Béarn, in the North-East of Pau, the first with Andoins and the second with Limendous.

They cross of is in west the Chalosse where they gather with the foot of the castle of Gaujacq, to join in Adour downstream from Tercis-the-Baths (in the south of Dax).
