Popayán is the capital of the Colombian department of Cauca. It is located in southwestern Colombia between the Western Mountain Range and Central Mountain Range. It has a population of 318,059 people, an area of 483 km², is located 1760 meters above sea level, and has an average temperature of 18 °C.
The town is well known for its colonial architecture and its contributions to Colombian cultural and political life. It is also known as the "white city" due to the color of most of the colonial buildings in the city center, where several churches are located, such as San Francisco, San José, Belén, Santo Domingo, San Agustín, and the Catedral Basílica Nuestra Señora de la Asunción, known locally as "La Catedral". The city's cathedral was home to the Crown of the Andes, a 16th-century Marianist devotional object featuring emeralds taken from the captured Inca Emperor Atahualpa. It was sold to finance local health care institutions.
Popayán has been home to seventeen Colombian presidents, as well as noted poets, painters, and composers.
