The sparkling white mudéjar (Moorish-style) cathedral, with its domes and colorful azulejos (blue Portuguese-style ceramic tiles), dominates the town. The black Virgen de Candelaria statue, carved by Francisco Yupanqui, is never moved from the cathedral, as superstition suggests that its disturbance would precipitate a devastating flood of Lake Titicaca.
The cathedral is a repository for both European and local religious art and the Museo de la Catedral contains some interesting articles. Don't miss the ostrich vases or the hundreds of paper cranes donated by a Japanese woman in the hope of bearing an intelligent child. There are group tours on demand.
