Agriculture is the economic base of the village. Irrigated lands were formerly less common than dry lands but, with the installation of a new irrigation system by the Community of Irrigators, irrigated lands increased significantly. The main cultivated products are vineyards, fruit trees, almond and olive trees. Crafts cane (reeds) and pottery were traditional in the past, although currently nonexistent.
Ginestar was under the rule of the Templars, from whom it received a town charter in 1206. Once l'Ordre del Temple was removed, the village was ruled by the Hospitalers.
It is worth mentioning the presence of King Martin the Humane in the village in 1409, who was spending some time in Tortosa, as well as Philip II's stay in the village in 1585, as part of his second trip to Catalonia.
