Where is the tallest monument in the world?

There is a world-famous arch in St. Louis, Missouri, USA. This is a parabolic building, which was designed in 1947 by the famous Finnish-born American designer Sharinan and made of stainless steel. People in St. Louis can see it wherever they go. This arch is the pride of St. Louis and the tallest monument in the world at present.

construction of the arch began in 1964 and was completed on October 28th, 1965. It is 192 meters high, and the distance between the two spans is also 192 meters, costing 29 million US dollars. On April 3, 183, the United States and France signed a treaty to buy and sell Louisiana for 15 million dollars. At the end of 183, Louisiana was transferred to the United States. The United States ensures that local residents enjoy the same rights as the American people and eventually make them join the Union. Therefore, this arch symbolizes the gateway of the road that Americans walked westward when they explored the western region in the early 19th century. It stands tall on the banks of the Mississippi River, which is both magnificent and romantic. The basement of the arch is quite wide, and there is also a museum, which shows the historical situation of a large number of immigrants going west at that time with materials such as objects and pictures. Although small in scale, it is full of vitality and gives people historical knowledge. It is said that as many as 4 million people come to visit each year.
