Cádiz is a coastal city in southwestern Spain and part of the autonomous community of Andalusia. It is the capital of the province of Cádiz. According to the 2004 census, the population of Cádiz proper is 133,242, while the population of the entire urban area is estimated to be 629,054. The city is located on a peninsula protruding into the Bay of Cádiz, part of much larger Gulf of Cádiz. Cádiz is of typical Andalusian character. The old part of Cádiz, commonly referred to as the Old City (Spanish Casco Antiguo), is shaped by the individuality of the various quarters (Spanish barrios), "El Populo," "La Viña," or "Santa Maria." These areas offer a marked contrast to the newer areas of town. While the townscape of the Old City is largely formed by narrow alleys leading into a number of plazas, newer areas consist of wide avenues and more modern buildings. In addition, the city is dotted by numerous park plants, including old giant trees supposedly brought there by Columbus.
