Situated high up in gardens on a gently sloped hill, the Belem Palace is the official residence of Portugal's president since 1910. It was built in 1559 and altered in the 18th century by King João V.
In 1755 King Jose I was inside the palace where the Great Earthquake was felt only to a slight extent, and just like most buildings in this area, it wasn't severely damaged. It still retains its richly furnished halls, carvings, tiles, and numerous works of art that may be visited on Saturdays only.
The Presidency Museum is part of the palace and can be visited every day except Mondays. tells the story of the Portuguese Republic and its Presidents, with a permanent collection explaining the history of the nationals symbols (flag and anthem) and the role of the presidents through photographs. In one gallery are portraits of every Portuguese president and in another are the gifts each received from world leaders and other prominent figures.
In front of the palace is a square with well-tended gardens and a statue of Afonso de Albuquerque, the Viceroy of India, standing atop a 20m-high Neo-Manueline pedestal in the center.
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.
