Situated on a narrow slice of land surrounded by the sea‚ Cádiz is, in most respects, a typically Andalusian city with a wealth of attractive vistas and well-preserved historical landmarks. The older part of Cádiz within the remnants of the city walls is commonly referred to as the Old Town (Spanish: "Casco Antiguo"). It is characterized by the antiquity of its various quarters ("barrios"), among them "El Pópulo", "La Viña", and "Santa María", which present a marked contrast to the newer areas of town. While the Old City's street plan consists of narrow winding alleys connecting large plazas, newer areas of Cádiz typically have wide avenues and more modern buildings. In addition, the city is dotted with numerous parks where exotic plants flourish, including giant trees supposedly brought to Spain by Columbus from the New World.
