This penitential popular pilgrimage has been held since the 19th century on the Day of the Holy Trinity
, the first Sunday after Whitsun. The bells start ringing at 8 a.m. and numerous people start the pilgrimage to the chapel of the Trinity. Standing on the edge of a rocky escarpment of the Leire mountain range
, the white of the chapel shines in the sun.
Penitents of the fraternity of Los Cruceros, dressed in black tunics, carry heavy wooden crosses and make the hard ascent up to the chapel, 740 metres above sea level
. The pilgrimage is made in line depending on the seniority of the penitents. The youngest in the front, the oldest at the back. The pilgrimage is characterised by its sobriety and spirituality and lasts for about an hour. Once at the chapel, Mass is celebrated and a festivity is enjoyed afterwards.
Tiene lugar en mayo o junio, el primer domingo después de Pentecostés (es decir, ocho domingos después del domingo de Semana Santa).
