The palaces of the king are enclosed in a fort of lofty walls, which have a circumference of three miles. The palace of the Chehel Sitoon, or "forty pillars," is situated in the middle of an immense square, which is intersected by various canals, and planted in different directions with the beautiful chenar tree. The palace was built by Shah Abbas. Under the great room are summer apartments, excavated in the ground, which, in their season, must be delightful retreats. They are also wainscoted, and paved with marble slabs; and water is introduced by cascades, which fall from the ground floor, and refresh the whole range. The Ali Capi gate forms the entrance. This gate, once the scene of the magnificence of the Seffi family, the threshold of which was ever revered as sacred, is now deserted, and only now and then a solitary individual is seen to pass negligently through. The remains of that splendour, so minutely and exactly described by Chardin, are still to be traced; the fine marble remains, and the grandeur and elevation of the dome, are still undemolished.[297] At the Ala Capi gate of the old palaces, which is described as one of the most perfect pieces of brick-work to be found in Persia, used to sit Shah Abbas, and thence review his cavalry, galloping and skirmishing, or witnessed the combats of wild animals[298]. In former times this view from the spot was undoubtedly splendid; but, at present, with the exception of the palaces in the gardens, the whole mass below is one mouldering succession of ruinous houses, mosques, and shapeless structures, which had formerly been the mansions of the nobility, broken by groups or lines of various tall trees, which once made part of the gardens of the houses now in ruins. The freshness of all the buildings is said to be particularly striking to an European, or the inhabitants of any comparatively humid country, in which the atmosphere cherishes a vegetation of mosses, lichens, and other cryptogamous plants, which we particularly associate in our minds with the spectacle of decay. Sir W. Ouseley says, "I explored the ruins of villages, scattered over the plain in all directions near our camp; and some must have been considerable in size and respectability from the handsome houses which they contained. Although pillaged and depopulated by the Afghans almost a century ago, many of their chambers yet remain, with vaults and staircases but little injured; yet no human being is ever seen within their walls, except some traveller, who wonders at finding himself alone in places, which might be easily rendered habitable, situate not above a mile from the walls of a great metropolis. It must be confessed, that these ruins, composed of sun-dried brick and mud, appear, like many edifices in Persia, to much greater advantage on paper than in reality."
