At the heart of Cuzco is the Plaza de Armas, with colonial arcades and four churches situated around it. The cathedral, built on the site of the Inca Palace of Viracocha and completed in the 17th century, exhibits both Renaissance and Baroque elements. It has a solid silver altar and a beautifully carved original wooden altar retable. The original designs for the 1-acre (4,000 m2) large construction were drawn by the Spanish architect and conquistador, Juan Miguel de Veramendi. Dedicated to Santo Domingo, but not to be confused with the church and convent of the same name.
