Luxor Temple is a large Ancient Egyptian temple complex located on the east bank of the Nile River in the city today known as Luxor (ancient Thebes) and was constructed approximately 1400 BCE. In the Egyptian language it was known as ipet resyt, 'the southern sanctuary'. It was one of the two primary temples on the east bank, the other being Karnak. Unlike the other temples in Thebes, Luxor temple is not dedicated to a cult god or a deified version of the pharaoh in death. Instead, Luxor temple is dedicated to the rejuvenation of kingship; it may have been where many of the pharaohs of Egypt were crowned in reality or conceptually (as in the case of Alexander the Great, who claimed he was crowned at Luxor but may never have traveled south of Memphis, near modern Cairo).
To the rear of the temple are chapels built by Amenhotep III of the 18th Dynasty, and Alexander. Other parts of the temple were built by Tutankhamun and Ramesses II. During the Roman era, the temple and its surroundings were a legionary fortress and the home of the Roman government in the area. During the Roman period a chapel inside the Luxor Temple originally dedicated to the goddess Mut was transformed into a Tetrarchy cult chapel and later into a church.
Along with the other archeological sites in Thebes, the Luxor Temple was inscribed on the UNESCO World Heritage List in 1979.
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.
