The Intrepid Sea, Air & Space Museum is an American military and maritime history museum in New York. The museum showcases the aircraft carrier USS Intrepid, the cruise missile submarine USS Growler, a Concorde SST, a Lockheed A-12 supersonic reconnaissance plane, and the Space Shuttle Enterprise. On the lower deck there is also a reproduction of a World War I biplane.
The museum opened in 1982 at Pier 86 after prominent New York real estate developers Zachary and Larry Fisher, and philanthropist and journalist Michael Stern saved USS Intrepid from scrapping in 1978.
In 1988, the museum was awarded USS Growler, a Grayback-class submarine, which carried nuclear Regulus missiles, by the United States Congress from the United States Navy. The submarine is on display after extensive renovations were performed in 2009.
In 2011, ownership of the Space Shuttle Enterprise was transferred to the Intrepid Sea, Air & Space Museum. To make room for the Enterprise display, three aircraft were transferred to the Empire State Aerosciences Museum near Schenectady, New York.
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.
