Las Lajas Sanctuary, Narino, Colombia
The most striking feature of this Catholic church is its setting: the grey stone structure spans a forested gorge 150 feet (46m) above a river. Its story is one of miracles and determination, beginning in 1754 when a mother and daughter, sheltering from a storm, saw an image of the Virgin Mary in the rocks. According to the story, the daughter was cured of her muteness and deafness. After hearing of the miracle, a blind man spent 10 years collecting funds to build a chapel in the spot – and his sight returned. Inspired by these marvels, the vertiginous church was finally built between 1916 and 1949.
