Meet the guide at a central point and start visiting the Santa Cruz district, known as the former Jewish quarter. This is the most picturesque and delightful part of the city, with narrow winding cobbled streets and whitewashed houses, where you can sit outside a bar, enjoy some tapas and watch the world go by, or wander through centuries-old gardens and relax on beautiful tiled benches. Wandering round the small squares lined with orange trees (especially Plazas Doña Elvira and Santa Cruz), getting lost in the maze of improbably narrow alleys, where the ancient houses lean so far towards each other that they almost seem to touch and admiring the leafy patios of private mansions through their iron gates; this will be one of the best experiences of your visit to Seville.  The main sights are the Cathedral and Giralda, formerly a minaret (mosque's tower), the Alcázar (royal fortified palace) and the baroque Hospital of the Venerables (originally a home for retired priests) whose chapel houses a fine collection of paintings as well as murals by Valdés Leal; the hospital also holds temporary exhibitions. The Archivo de Indias, which houses all maps and documents about Spain's conquest of the New World, is open to the public and stages frequent exhibitions, as well as offering an unparalleled historical resource. After the walking tour, enjoy of a nice one-hour cruise, during which you will discover the city from another perspective, the one of its legendary river Guadalquivir.
