The Casa de los Dragones on Plaza de los Reyes is a fantastic dream that has entered the real world. Recently restored to perfection, this former home is an extraordinary example of eclectic architecture, with Moorish arches, polished brick facades, Mansard roofs, fabulous balconies, and the pièce de résistance, four enormous dark dragons springing from the roof. Unfortunately, it's not open to the public. The intricate anagram of the Cerni Gonzalez Brothers, the builders, is emblazoned on the corner. Tip your hat.
