Markets and merchants, and its people are prosperous, possessing wealth and influence. There are extensive dealings with the Arabs, and participation in plowing and storing grain. Wheat stored there in its granaries remains unspoiled for a hundred years. Honey is abundant there, as is clarified butter, which is exported from there to all other lands. The city of Fasdilitah is situated on the impregnable mountain of Mimna', which is somewhat circular. It can only be reached from one direction through a gate in the west, which is not very wide. There are the tombs of its people, where they bury their dead. Near the tombs, there is also a standing structure, like the ancient Roman buildings. Within it is a palace, almost entirely ruined except for a small part. There is also a stadium, built in the Roman style, similar to the stadium of Tarmata in Sicily. This city, meaning Constantinople, is surrounded by a valley on all sides, like a ring. The city has an inner wall, more than half a person's height, except for the direction of the Bab Mila gate. The city has two gates: Bab Mila in the west and Bab Al-Aitharah in the east. This Al-Aitharah is one of the wonders of construction, as its height exceeds a hundred cubits by the Rashashi cubit. It is a Roman construction, called 'Ulya 'ala Fassi Su'la. Its number in the width of the valley is five. Water enters through three of them from the west side. They are, as we have described, arch upon arch. The first arch carries the water at the bottom of the valley, and the other arch is above it. On its back is the walkway and passage to the second level. The remaining two arches, which are from the city's side, stand individually on the mountains. The arch and the arch show legs that support the water and its flow. The number is Hammad, with its base. On the necks of the legs are empty arches, like small pillars. When the water level rises at times, it flows over the legs, and through those openings. It is one of the wonders.
