The Thomas Jefferson Memorial is a presidential memorial dedicated to Thomas Jefferson (1743–1826), one of the most important of the American Founding persons. Jefferson was the main drafter and writer of the Declaration of Independence, member of the Continental Congress, governor of the newly independent Commonwealth of Virginia, American minister to King Louis XVI and the Kingdom of France, first U.S. Secretary of State under the first President George Washington, the second Vice President of the United States, and also the third President (1801–1809).
The neoclassical Memorial building on the Tidal Basin off the Washington Channel of the Potomac River was designed by the architect John Russell Pope and built by the Philadelphia contractor John McShain. Construction of the building began in 1939 and was completed in 1943. The bronze statue of Jefferson was added in 1947.
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.
