The National Shrine Basilica of Our Lady of Las Lajas, commonly called Las Lajas Shrine, is a basilica church located in southern Colombia. The basilica is situated within the municipality of Ipiales, in the Nariño Department, and is built inside the canyon of the Guáitara River.
The present church was built in a Gothic style between 1916 and 1949. The name Laja comes from the name of a type of flat sedimentary rock similar to shale and slate.It is a popular pilgrimage site for Christians from both Colombia and neighboring Ecuador, due to a Marian apparition that is purported to have taken place here in the 18th century.
