It was created in 1977 when the communities of Jesús i Maria and la Cava ceceded from the municipality of Tortosa: the ajuntament (town hall) is in la Cava. The municipality occupies much of the northern half of the Ebre delta, on the left bank of the river. The cultivation of rice and tourism are the major industries. The T-340 road links the municipality with Tortosa and the rest of the comarca, while barges cross the river to Sant Jaume d'Enveja.
