The foundation of the White House was chosen by George Washington, the founding father and first president of the United States, and was built in 1792 and almost completed in 1800 by the famous Irish-American architect James Horburn. But it was not called the White House at the time, and the "White House" was officially named by President Theodore Roosevelt in 1902.

Built in March 1930, the Empire State Building in New York was the lightest building of its time, built during the economic crisis in the West, became a symbol of America's economic recovery, and is still a permanent symbol of New York City along with Lady Liberty. It was once the tallest building in the world and a landmark of New York City. One of the Seven Engineering Wonders of the World, it continued to take over the title of New York's first building after the collapse of the World Trade Center in 911 until the completion of the Freedom Tower.

3 Statue of Liberty

The Statue of Liberty, also known as Liberty Enlightening The orld, was a gift from France to the United States in 1876 for the 100th anniversary of its independence.

4 Capitol Building

Located on the 25-meter-high Capitol Hill in Washington, D.C., the Capitol Building is the heart of the United States. The Capitol was built between 1793 and 1800, and like many important buildings in Washington, D.C., it was not spared the destruction of the Anglo-American War in 1814.

After the post-war reconstruction, the Houses of Parliament underwent several expansions over the centuries, including a massive reconstruction project from 1851 to 1867, to finally form the current form. The Parliament Building is a three-story building with a total length of 233 meters, made of white marble, and a large three-story dome on the central top floor, on which a 6-meter-high bronze statue of Lady Liberty stands. The north and south wings on either side of the dome are home to the House of Representatives and the Senate, respectively.

For the groundbreaking of this project, the organization called the National Monument Preparation Association, which has been raising funds nationwide for 15 years. By the time of the Civil War in 1854, the monument had been suspended due to the war for about 50 meters. In 1876, construction of the Washington Monument finally began, and by 1885 it was fully completed, with a total height of 169 meters. The white marble of the Washington Monument is slightly darker than the one below, about 50 meters above, and is the result of two sections of construction 22 years apart.

The Washington Monument is a stone obelisk with a tall cube column topped by a triangular spire on all sides. The interior of the Washington Monument is hollow, and there are 193 stone tablets donated by various countries, states and cities in the United States, major organizations and celebrities on its inner wall, including the Wenyan stone tablet donated by the Ningbo Mansion of the Qing Dynasty, and the text on the tablet is taken from the "Yinghuan Zhiluo" by Xu Jishe, the governor of Fujian.

7 Pentagon

The Pentagon was founded in August 1941. In early 1941, Hitler took control of much of the European continent, and then-US President Franklin D. Roosevelt declared a national emergency. The burgeoning U.S. War Department (which existed from 1789 to 1947) was in dire need of a new command base, and the Pentagon began construction.

The Pentagon is the world's largest single office building by floor area, with a total floor area of 6.5 million square feet (604,000 square meters), of which 3.7 million square feet (344,000 square meters) are office. About 23,000 military and civilian personnel work at the Pentagon, and about 3,000 non-defense volunteers serve at the Pentagon. The Pentagon has five facades, and the building is divided into five floors (including two basement levels), each with five circular corridors from the inside to the outside, with a total length of 17.5 miles (28.2 kilometers).

9 Golden Gate Bridge

The Golden Gate Bridge is one of the world's famous bridges and a miracle of modern bridge engineering. Standing majestically over the 1,900-meter-long Golden Gate Strait in California, the bridge took four years and more than 100,000 tons of steel to build, costing $35.5 million and was designed by Strauss. The Golden Gate Bridge is one of the world's most famous bridges, hailed as a miracle of modern bridge engineering and considered a symbol of San Francisco.

The Golden Gate Bridge was designed by engineer Strauss, and a bronze statue of him was placed on the side of the bridge to commemorate his contributions to the United States. The bridge stands majestically over the 1,900-meter-wide Golden Gate Strait in California, USA. The Golden Gate Strait is the entrance to San Francisco Bay, with steep banks and deep waterways, discovered and named by the English explorer Francis Drake in 1579.

The northern end of the Golden Gate Bridge connects Northern California to the southern end to the San Francisco Peninsula. When the ship sails into San Francisco, the first thing that catches your eye from the deck is the giant steel tower of the bridge. The steel towers stand on the north and south sides of the bridge and are 342 meters high, of which 227 meters above the water are divided, which is equivalent to a 70-story building. Construction of the Golden Gate Bridge began in 1933 and was completed in May 1937, taking four years and more than 100,000 tons of steel at a cost of $35.5 million. The whole bridge is magnificent and unpretentious. The vermilion color of the bridge lies on the blue sea and white waves, and the lights are first released, like a giant dragon volleying in the sky, making the night sky of San Francisco more magnificent.

10 Separate Halls

The Independence Hall is a Georgian-style red brick building located in Philadelphia, Pennsylvania, United States. It was built between 1732 and 1753 and was designed by Edmund Oolley and Andrew Hamilton, with Woolley directing the building. The highest point of the building is 41m (135ft) above the ground. The building was originally approved by the Pennsylvania colonial legislature as the seat of the Pennsylvania colonial legislature. Two other small buildings are adjacent to the Independence Hall: the Old City Hall on the east side and the Congress Hall on the west side. On July 4, 1776, representatives from the thirteen states of North America under British colonization signed the Declaration of Independence of the United States, written by Thomas Jefferson. In 1787, the U.S. Constitution was also enacted here. During the period from 1790 to 1800, when Philadelphia was the capital of the United States, the building was the seat of the United States Congress.
