The National Theatre is located in Washington, D.C., and is a venue for a variety of live stage productions with seating for 1,676. Despite its name, it is not a governmentally funded national theatre, but operated by a private, non-profit organization.
This historic playhouse was founded on December 7, 1835, by William Corcoran and other prominent citizens who wanted the national capital to have a first-rate theatre. The theatre's initial production was Man of the World. The theatre has been in almost continuous operation since, at the same Pennsylvania Avenue location a few blocks from the White House. The structure has been rebuilt several times, including partial reconstructions after five fires in the 19th century. The current building, at 1321 Pennsylvania Avenue NW, was constructed in 1923, opening in September of that year.
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.
