The frowning old Alcazar on the cliff overlooking the Manzanares, so often mentioned as the scene of Philip's festivities, was unfit for gaiety, and offered but few attractions to him. The Escorial for similar reasons was never a favourite residence of his; and Aranjuez was always insalubrious except in the spring. The Court therefore was usually in residence in Madrid itself, or in the neighbouring hunting seat of the Prado. But there was in the extensive and beautiful grounds attached to the monastery of St. Geronimo at the east gate of the capital a suite of apartments used {239} by the royal family for religious or mourning retreats, or for an occasional guest house. It occurred to Olivares in 1631 that this place might be made more attractive, and used more frequently as a relief to Philip from the stern mediæval palace at the other end of the town. The idea began with the mere levelling of an inequality here, the clearing of a lawn there, and the building of an aviary and a few fountains and summer houses. But very soon the Count-Duke's ambition grew, and he and Philip became fascinated and absorbed in the building of a palace which became to the reign of Philip what Versailles was to that of Louis XIV. [Sidenote: The Buen Retiro] The palace of the Buen Retiro was intended by Olivares, and truly was, a fit setting for the elegant, chivalric, and poetic surroundings of the King, a light and pretty retreat in the midst of enchanting gardens, where upon stages under the trees or in high and gilded halls the witty dissolute comedies might be played to an audience of the elect. Nothing that the inspiration of genius, the efforts of flattery, or the exercise of unrestrained expenditure could compass was spared by Olivares in making the Buen Retiro perfect for its purpose of keeping the King diverted. An immense territory, in addition to the monastery grounds, was appropriated for the purpose,[23] and Olivares exhausted all the horticultural knowledge of the time in laying out {240} the grounds with lakes, grottoes, and cascades; whilst in a very short time there arose in all its beauty the palace that in future was to be the symbol of Philip's elegant, picturesque, but useless reign.
