The Church and Monastery of St. Francis (Spanish: Iglesia y Monasterio de San Francisco), commonly known as el San Francisco, is a 16th-century Roman Catholic complex in Quito, Ecuador. It fronts onto its namesake Plaza de San Francisco. The imposing structure has the distinction of being the largest architectural ensemble among the historical structures of colonial Latin America and for this reason is sometimes known as "El Escorial of the New World". The style evolved over almost 150 years of construction (1534-1680) through earthquakes and changes in artistic fashion.
