The formal gardens immediately below the Palacio Real, laid out in the English landscape style in the 19th century and occupying the slope that descends from the palace to the Manzanares river. The name comes from the Almoravid army that camped here in 1109, though the gardens themselves date from successive royal redesigns in the 19th century.
The park is quiet, well-maintained, and largely empty compared to the tourist crowds on the palace side. Peacocks wander freely. The fountains and garden buildings are on the historic register. Access is through a gate on the river side; the approach from Príncipe Pío station is the easiest route. Open daily except Mondays and Tuesdays; free entry.
