Cádiz is on the Andalusian coast of Spain called Costa de la Luz. The peninsula where the city is located has one narrow connection to the mainland. The rest of the seven mile circumference is surrounded by water. The longest and among the best seafront promenades is Avenue Campo del Sur. The serpentine path follows a breakwater tracing the southern coast along Mar del Vendaval (Gale Sea). Although partially concealed by piles of large cinder blocks, the seawalls are sections of the defenses once encircling Cádiz.
