Quito, Ecuador's capital, sits high in the Andean foothills at an altitude of 2,850m. Constructed on the foundations of an ancient Incan city, it’s known for its well-preserved colonial center, rich with 16th- and 17th-century churches and other structures blending European, Moorish and indigenous styles. These include the cathedral, in the Plaza Grande square, and ultra-ornate Compañia de Jesús Jesuit church.
