Medinet Habu is an archaeological locality situated near the foot of the Theban Hills on the West Bank of the River Nile opposite the modern city of Luxor. Although other structures are located within the area and important discoveries have also been made at these sites, the location is today associated almost synonymously with the largest and best preserved site, the Mortuary Temple of Ramesses III.
The site of these temples included an inhabited human settlement since pharaonic times, which continued until the 9th century, by which time it was a Coptic center. The last remnants of the former town were cleared during the excavations at the end of the 19th century.
Just right of the entrance to the Mortuary Temple of Ramesses III is the Temple of Amun, dating to the 18th Dynasty, built by Hatshepsut and Thutmose III. It has undergone many alterations and modifications over the years, partially in the 20th, 25th, 26th, 29th and 30th dynasties and the Greco-Roman period.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
