La Marisma is the name of a 'comarca' (region or area) in the south west of the province of Seville. It is made up from 4 municipal districts and other small villages.
The municipal districts are El Cuervo, Isla Mayor, Las Cabezas de San Juan and Lebrija.
The largest town is the farming town of Lebrija, famous wine production and pottery.
El Cuervo only actually gained independence at the start of the nineties.
The town is located close to the Marismas del Bajo Guadalquivir that occupy part of Doñana nature park. More >
