Introduction to the Arc de Triomphe: The Triumphal Arch is a European building that commemorates war victory. It was built in the ancient Roman period as a way for the rulers to show off their achievements. It was later followed by other European countries. Often built in the main streets or squares of cities. It is built with stones and looks like a gatehouse. It has one or three arched door openings and is engraved with reliefs to promote the achievements of the ruler. The Arc de Triomphe in the Place de l'Etoile in Paris, France, also known as the Arc de Triomphe in Place Charles de Gaulle, was built in 1806 during the heyday of the French Emperor Napoleon I's regime. This is the largest of the more than 100 triumphal arches in Europe. It is one of the four representative buildings in Paris and a historic site protected by the French government.
