Approaching it from the south, the traveller first observes a triumphal gateway, nearly entire, bearing a striking resemblance in point of workmanship to the remains of Antinoë in Upper Egypt. The front presents four columns of a small diameter, and constructed of many separate pieces of stone; their pedestals are of a square form, but tall and slender. On each of these is placed a design of leaves, very like a Corinthian capital without the volutes; and on this again rises the shaft, which is plain, and composed of many small portions. As all the columns were broken near the top, the crowning capitals are not seen. The pediment and frieze are also destroyed; but enough remains to give an accurate idea of the original design, and to prove that the order of the architecture was Corinthian. The building appears to have been a detached triumphal arch, erected for the entrance of some victorious hero passing into the city. Just within this gateway is perceived an extensive naumachia, or theatre for the exhibition of sea-fights, constructed of fine masonry, and finished on the top with a large moulding wrought in the stone. The channels for filling it with water are still visible. Passing onward there is seen a second gateway, exactly similar in design to the one already mentioned, but connected here on both sides with the walls of the city, to which it seems to have formed the proper entrance. Turning to the left the stranger advances into a large and beautiful colonnade arrange in a circular form, all of the Ionic order, and surmounted by an architrave. He next perceives beyond this point a long avenue of columns in a straight line, supposed to mark the direction of some principal street that led through the whole length of the town. These columns are all of the Corinthian order, and the range on each side is ascended to by a flight of steps.
