The Great Wall of China is the largest man-made structure in the world; it is visible from space, and has been photographed from space. Oct 01 00, 2:43 AM

The Petronas Towers are the 'tallest', but the question asks for the largest which is volume. The Great Wall of China has greater volume, hence is the largest. On another note, the Petronas Towers are the tallest buildings, but NOT the tallest man made structure. The CN Tower in Toronto is still 100 meters taller than Petronas. Oct 12 00, 9:37 AM

pl1	In 1991, the Great Wall of China became the second largest man-made structure in the world. The largest was Fresh Kills Landfill, serving New York City. It is now the highest point on the east coast. Jan 05 07, 5:52 AM

PieDish is CORRECT. " Opened in 1948, it became one of the largest refuse heaps in human history. The site is 12 square km (4.6 square miles) in area; and when operational twenty barges, each carrying 650 tons of rubbish, were shipped in every day.[2] Had Fresh Kills stayed open as long as originally planned it would have grown to be the highest point on the East Coast of the United States. It could be regarded as being the largest man-made structure on Earth, with the site's volume eventually exceeding the Great Wall of China. In fact in 2001 its peak was 25 meters taller than the Statue of Liberty. " http://en.wikipedia.org/wiki/Fresh_Kills_Landfill Dec 29 07, 6:02 PM

As for "Highest Point on the East coast"....Heck no! Mt. Washington. " Mount Washington is the highest peak in the American Northeast at 6,288 ft (1,917 m). " http://en.wikipedia.org/wiki/Mount_Washington_(New_Hampshire) As for GWoC being visible from space.....As Baloo might say...Rubbish! http://www.space.com/scienceastronomy/great_wall_031017.html " For some reason, some urban legends tend to get stated and never disappear. This legend even appears as a erroneous Trivial Pursuit question. The legend? Many are familiar with the claim that the Great Wall of China is the only man-made object visible from space or from the moon with the naked eye. This is simply not true. " http://geography.about.com/od/specificplacesofinterest/a/greatwall.htm " It has become a space-based myth. The Great Wall of China, frequently billed as the only man-made object visible from space, generally isn't, at least to the unaided eye in low Earth orbit. It certainly isn't visible from the Moon. " http://www.nasa.gov/vision/space/workinginspace/great_wall.html As for the highest/tallest man made structure.... " The tallest standing structure is the KVLY-TV mast 30 miles (48 km) north of Fargo, North Dakota United States, at 628.8 m (2,063 ft). It is a transmission antenna, consisting of a bare metal structure supported by guy-wires. " http://en.wikipedia.org/wiki/Supertall#Tallest_structures Dec 29 07, 6:07 PM
