Some national holidays feel casual, almost effortless — picnics, beach days, music drifting from open windows. October 12 in Spain is not one of those days. It arrives with formality, uniforms, symbols, and a kind of choreography that feels inherited rather than invented. The morning belongs to precision, ceremony, and centuries of story; the night belongs to celebration and fire. The photograph from the parade captures the first heartbeat of the day: ranks of horses moving down a wide Madrid boulevard, their steps measured and unhurried.
