The Triumphal Arch of Leon, or Arco de la Calzada, is one of the city's easiest landmarks to love: a ceremonial arch crowned by a bronze lion, standing at the entrance to the Calzada de los Heroes.
It is best seen as part of an evening walk, when the surrounding avenue fills with people and the arch becomes a meeting point rather than just a monument. The sight is quick, but it gives Leon a clear civic emblem.
