Ecuador's capital is old, and it looks it. Founded in the 16th century, ruins of the inca city still stand. Much of the city is a UNESCO World Heritage site. According to UNESCO:
Despite the 1917 earthquake, the city has the best-preserved, least altered historic centre in Latin America. The monasteries of San Francisco and Santo Domingo, and the Church and Jesuit College of La Compañía, with their rich interiors, are pure examples of the 'Baroque school of Quito', which is a fusion of Spanish, Italian, Moorish, Flemish and indigenous art.
It's not a major destination, but Quito is trying to change that, launching an aggressive tourism push. Below, scenes from the city.
