Village · Isla Mayor, Comarca Metropolitana de Sevilla, Seville

Municipality of 5,748 inhabitants (2025) and 114.51 km², at just 5 m altitude deep in the Guadalquivir marshes. Alfonso X granted these former river islands to the city of Seville in 1253 for cattle grazing; the British company Islas del Río Guadalquivir introduced rice cultivation in the 1930s, and from the 1940s General Queipo de Llano promoted the colonization of the marshes with families from Andalusia, Extremadura, and Valencia. The American red swamp crayfish arrived in 1974. It split off administratively from La Puebla del Río in 1994 and adopted its current name in 2000.
