La Merced Church and Convent
Erected in 1536 and rebuilt in 1680 after the great earthquake, this Minor Basilica and convent has a beautiful facade, fine cloisters, and two famous conquistadors buried in the crypt.
This Baroque cathedral was built on the foundations of the palace of the Inca Wirachocha. Construction began in 1550, using stones looted from the hillside Sacsayhuaman fortress, and completed a century later. It is considered one of the most splendid Spanish colonial churches in the Americas.
Built in 1656 and reconstructed after an 1868 earthquake, Arequipa Cathedral is a fine example of Spanish colonial architecture but is especially notable for its immense size. Its huge facade dominates an entire side of the Plaza de Armas in the center of the city. Inside is the largest organ in South America, a gift from Belgium.
The main draw of this archaeological museum is its collection of Inca mummies. The museum is housed in a splendid colonial mansion, which was built over an Inca palace.
La Compañía de Jesús
The elegant Church of the Society of Jesus rivals Cusco's cathedral in grandeur. Like the cathedral, it was also built on the site of an important ancient palace, that of the Inca Huayna Cpac.
Designed by Pizarro himself, this immense baroque cathedral also contains the conqueror's tomb.
A high plateau in southern Peru is home to the remarkable Nazca Lines - giant earth drawings of a hummingbird, monkey, spider, lizard, and other shapes created between 200 BC and 600 AD.
Santa Catalina Convent and Museum
The Monasterio y Museo de Arte de Santa Catalina was built between 1601 and 1610 over the ruins of the ancient Acllawasi, the "House of the Sun Virgins." It has fine frescoes and a good collection of paintings.
