Time Out says
This vast garden was named after a Muslim leader in the Middle Ages, Ali Ben Yusut, who attempted to capture the fortress that is now the Palacio Real. Unfortunately, it is only accessible from the Paseo de la Virgen del Puerto side, requiring a fairly long walk down Cuesta de San Vicente or Cuesta de la Vega. As a reward, however, you'll find a quiet, leafy garden (in complete contrast to its surroundings) with two fine monumental fountains where you can see peacocks and forget about the outside world. The fountain nearest the palace is Los Tritones, originally made in 1657 for the palace in Aranjuez; the other is Las Conchas, designed in the 18th century by Ventura Rodríguez. Both were moved here in the 1890s.
