Arequipa
Arequipa is the colonial-era capital of Peru’s Arequipa Region. Framed by 3 volcanoes, it's filled with baroque buildings constructed from sillar, a white volcanic stone. Its historic center is anchored by the Plaza de Armas, a stately main square flanked on its north by the 17th-century neoclassical Basilica Cathedral, which houses a museum displaying religious objects and artwork.
