The design of the arch by Jean Chalgrin is based on the Arch of Titus in Rome. The Arc de Triomphe is much higher (50m versus 15m), but it has exactly the same proportions.
The arch is located at the end of the Champs-Elysées, in the middle of the Place Charles de Gaulle, a large circular square from which no less than 12 streets emanate. The streets are named after French military leaders.
The arch was commissioned by Napoleon in 1806 to commemorate his victories, but he was ousted before the arch was completed. In fact, it wasn't completed until 1836 during the reign of Louis-Philippe. The Arc de Triomphe is engraved with names of generals who commanded French troops during Napoleon's regime.
