The Basilica Cathedral of Arequipa ("Basílica Catedral", in Spanish) is located in the "Plaza de Armas" of the city of Arequipa, province of Arequipa, Peru. It is the most important Catholic church of the city and also of the larger Roman Catholic Archdiocese of Arequipa since it is the base of the archbishop and the metropolitan council. The cathedral is also considered one of Peru's most unusual and famous colonial cathedrals since the Spanish conquest. Timeline August 15, 1540: This is the date in which the city was founded by Garcí Manuel de Carbajal. The cathedral started construction on this very date.
