The Sénia Territory, a land of millenary olive trees, comprises 27 villages located on both sides of the Sénia river and around Tosal del Rey, where Aragon, Catalonia, and the Region of Valencia meet.

Nowadays there are 6.358 registered specimens which trunk has a perimeter greater than 3,50 m measured at 1,30 m above the ground, the predominant variety being Farga.
