Walls here's the link this is at the bottom

"Throughout history, nations have built walls to keep people in, keep people out or both.

Great Wall of China: One of the greatest construction projects in world history, the Great Wall runs, with branches, about 4,500 miles. Large parts of it date from the seventh through fourth centuries B.C. Built of dirt, stone and brick, the wall ranges from 15 feet to 25 feet wide and 15 feet to 30 feet tall with a 13-foot-wide road on top and watchtowers at regular intervals.

Berlin Wall: The barrier that separated West Berlin from East Berlin and surrounding areas in the former East Germany from 1961 to 1989 was a series of concrete walls up to 15 feet high topped with barbed wire and enhanced with watchtowers, stationary guns, mines and electrified fencing. By the 1980s, the wall ran 75 miles around West Berlin and 28 miles through Berlin.

Morocco / Western Sahara: The Moroccan Wall is a 1,600-mile system of sand berms and rock walls built in the 1980s by Morocco to control Western Sahara, where tensions continue between Morocco and Polisario Front separatists despite a U.N.-brokered cease-fire. The wall is an earthen mound about 7 feet high fronted by a 23-foot-wide ditch and studded with bunkers, barbed wire, and anti-personnel and anti-tank mines.

India / Bangladesh: India has built more than 1,300 miles of a planned 3,034-mile barrier at its border with Bangladesh. The fence will be patrolled by 50,000 officers and key stretches will be electrified. Construction of the $1 billion double fence -- which is 10 to 12 feet high, floodlit and razor-wire filled -- began in 1986 and will be done next year. It may extend near a demilitarized zone separating the two countries, to enclose Indian villages on the border.

Israel: Israel has built about 170 miles of the barrier separating it from the Palestinian-dominated West Bank. Another 140 miles are planned or under construction, and 155 more are under review. The barrier, a wire fence in some places and concrete wall in others, has additional enhancements such as barbed wire, electricity, sensors, watchtowers and sniper posts. Supporters say it has been routed to foil terrorists and critics say it unfairly incorporates Palestinian land into Israel.
