About half a dozen blocks west of the Plaza San Martín, on a traffic-choked thoroughfare, resides the Museo de la Cultura Peruana, a repository of Peruvian folk art. The collection, consisting of elaborate retablos (religious dioramas) from Ayacucho, historic pottery from Puno and works in feather from the Amazon, is displayed in a building whose exterior facade is inspired by pre-Columbian architecture.
