These extremely beautiful gardens slope westward from the Royal Palace toward the River Manzanares. Named after a medieval Arab chieftain who attempted a vain siege of the fortress that occupied the spot where the palace now stands, the park boasts a well-tended profusion of lawns, trees, and flowers. The park also has two magnificent fountains: the 17th-century Triton, originally located in the Aranjuez Palace gardens, and the Las Conchas, built by Ventura Rodríguez a century later. (Incidentally, the still signposted Museo de Carruajes, or Carriage Museum, tucked away in a corner of the grounds, has been closed for many years.) You can only enter the park from the lower side beside the Paseo de la Virgen del Puerto (which involves a longish roundabout walk via Cuesta de la Vega, if you are visiting the Royal Palace first).
