The Washington Monument is a granite obelisk lined with Maryland marble 169 meters high and weighing 91,000 tons. The largest obelisk in the world and the tallest structure in Washington D.C. There is not a single skyscraper in the city itself and, according to tradition, no building can exceed the height of the Washington Monument, although there is no specific law on this restriction.
It was built in 1848-1884 in Washington, between the White House and the Capitol, according to Robert Mills's design as a monument to the first US President, George Washington. Before the Eiffel Tower was built, it was the tallest structure on Earth. You can climb to the top of the monument by taking 896 steps or by using an elevator. On the east side, two Latin words “Laus Deo” are carved at the top of the monument, which means “Praise God”.
