Las Lajas in Colombia..
Las Lajas Sanctuary (in Spanish Santuario de Las Lajas) is a basilica church located in the southern Colombian Department of Nariño, municipality of Ipiales and built inside the canyon of the Guáitara River.
The cathedral is of Gothic revival architecture and was built from January 1, 1916 to August 20, 1949, with donations from local churchgoers, replacing an old nineteenth-century chapel. The name Laja comes from the name of a type of flat sedimentary rock similar to floor tiles found in the Andes Mountains. There was a claim that an apparition of the Virgin Mary was seen. There is now a miraclous image on a stone there. It is still possible to see this today.
