It is clear that the Aragonese court at Naples introduced the Moorish garden traditions of Valencia, with its shaded avenues and baths, sophisticated hydraulics that powered splendid waterworks, formal tanks, fishponds and fountains, as a luxurious and secluded setting for court life, and combined them with Roman features: Alfonso's Poggio Reale was built around three sides of an arcaded courtyard with tiers of seating round a sunken centre that could be flooded for water spectacles; on the fourth side it opened onto a garden that framed a spectacular view of Vesuvius.
