The Gateway Arch is the name given to a monument of 630 feet, found in St. Louis Missouri on the Mississippi River west bank. It is all covered with stainless steel and has the shape of an inverted catenary arch. It is the tallest arch in the world and the tallest building in Missouri that is accessible. It was built as a monument to form the centerpiece of Jefferson National Expansion Memorial and with time, it became a symbol of St. Louis that is famous internationally.
The design of the Gateway Arch was done by a Finnish-American architect called Eero Saarinen in the year 1947. The construction began 16 years later and was completed in 1965. It became open to the public on the 10th of June in 1967.
The Gateway Arch has a height of 192 meters (630 feet), which is the exact same measurement for the width. It is the tallest memorial in all the states of the US and the tallest monument made of stainless steel in the entire world.
Its legs have the cross section of an equilateral triangle which narrow from sides of 54 feet at the bottom to 17 feet at the top. All the walls consist of skin made of stainless steel that covers reinforced concrete sandwiched by two carbon-steel walls. The inside of the arch is hollow, accommodating a tram system which takes visitors to the top deck where there is an observation deck.
