The square is built primarily of sillar, a porous, white volcanic tuff stone unique to the Arequipa region.
The central fountain's statue, 'El Tuturutu,' reportedly represents a trumpet player who announced news in the colonial era.
The Basilica Cathedral has been reconstructed multiple times due to frequent seismic activity, with the current iteration dating primarily to the 19th century.
The plaza occupies the exact location of the city's original founding in 1540 by Spanish colonizers.
The arcades surrounding the square are known as 'portales' and were historically used by colonial merchants for trade.
Arequipa is known as the 'White City' specifically because of the predominant use of sillar in the plaza and surrounding historic district.
The cathedral contains a massive pipe organ imported from Belgium in the 1870s.
Plaza de Armas Arequipa is the primary public square of Peru’s 'White City,' defined by its uniform construction from white volcanic stone known as sillar. The square is framed on three sides by colonial arcades with stone arches and balconies, while the north side is dominated by the Basilica Cathedral of Arequipa. The central feature is a bronze fountain topped by a 19th-century statue of a mythical soldier figure called 'El Tuturutu.' The square underwent significant restoration following the 2001 earthquake to repair structural damage to its historic colonial facades. The open layout provides unobstructed views of the Misti, Chachani, and Pichu Pichu volcanoes on clear days. It serves as the historic center of the city, which is designated as a UNESCO World Heritage site. Unlike many colonial squares, the cathedral spans the entire length of the plaza's northern flank.

Maintain a respectful tone near the cathedral entrance; modest dress is expected if entering religious spaces.
