The actual city of Huelva dates back some 3000 years when it was named Onuba. Later, it prospered under the Cathaginians and Romans who used it as a base for mining. Three of the key sites of the Columbus story can also be found here - Lugares Colombinos. Today it is large, sprawling and industrialised with a population of 141,000. Heavy industrial plants line much of its Odiel waterfront and stretch far to the south. The city centre is pleasant and it is a convenient base for visiting the nearby Columbus sites or the Marismas del Odiel wetlands and the Coto Dónana national park. Huelva claims to be a 'flamenco capital', however several of the city's splendid old buildings and monuments remain, including the 15th century Church of San Pedro, built on the site of a mosque; the Shrine of Nuestra Senora de la Cinta and, last but not least, the home of Christopher Columbus next to his commemorative monument.
