Deltebre Winter Main Festival Activity · Deltebre, Baix Ebre, Tarragona Image of Deltebre, not of the place itself. Deltebre's Festa Major d'Hivern is held in the municipality established on 20 May 1977 on separating from Tortosa, uniting the former hamlets of Jesús i Maria and la Cava; the opening of the Canal de l'Esquerra in 1912 had earlier completed the rice-growing irrigation of this side of the delta.
