Amsterdam, the capital of the Netherlands and the largest city, has a population of about 1.1 million. Located in the western province of the country, North Holland, a world-famous international metropolis. Its name is derived from Amstel dam, which indicates the origin of the city: a dam on the Amstel River, now the Dam Square. According to the 2017 Urban Security Survey, Amsterdam was rated as the safest city in Europe. A small fishing village was built here in the late 12th century, and then due to the development of trade, Amsterdam became the world's important port in the golden age of the Netherlands. At that time, the city was the center of finance and diamonds. In the 19th and 20th centuries, the city expanded and many new neighborhoods were formed with suburban residential areas. Now it is the fourth largest airport in Europe.
