Within this last wall is the palace of the great khan, which is the largest and most magnificent of any in the world, extending the whole way between the north and south walls of the inner circuit, except an opening of sufficient width for the passage of the soldiers and barons attending the courts The palace hath no ceiling, but the roof is very high. The foundation of the pavement or floor is raised ten palms above the ground, and is surrounded by a marble wall of two paces wide, resembling a walk; and at the end of the wall without, there is a fair turret ornamented with pillars. In the walls of the halls and chambers, there are numerous figures of dragons, soldiers, birds and beasts of various kinds, and representations of battles, all finely carved and splendidly gilded, and the roof is so richly ornamented, that nothing is to be seen but splendid gold and imagery. In every square of the palace there is a great hall, capable of containing a prodigious multitude of people, and all the chambers are arranged and disposed in the best possible manner; the roofs being all richly painted red, green, azure, and all other colours. Behind the palace there are many great rooms and private storehouses, for the treasure and jewels of the khan, for the dwellings of his women, and for various other private purposes. Over against the palace of the khan, there is another, which was formerly inhabited by his deceased son Zingis, who held a court in all things resembling that of his father. Near the palace, and to the north, there is a high artificial mount, a mile in circumference, and an hundred paces high, planted with evergreen trees, which were brought from remote places, with all their roots, on the backs of elephants: This eminence is called the Green Mountain, and is extremely pleasant and beautiful. Where the earth was taken away to form this mount, there are two lakes corresponding with each other, supplied by a small river, and well stored with fish; and the passages of the water are grated in such a manner that the fish cannot escape.
