Centro Historico de Arequipa and the architecture of sillar

Centro Historico de Arequipa gives Peru’s southern city a pale volcanic-stone centre, where arcades, courtyards and carved façades meet.

Centro Historico de Arequipa is a city centre built in pale volcanic sillar, a material visible across churches, houses, arcades and courtyards. The stone cityscape belongs to Arequipa, southern Peru, and its architectural language combines European forms with native building traditions.

Sillar across the streets of Arequipa

Sillar is volcanic tuff, quarried from deposits associated with the volcanoes surrounding Arequipa. Its light colour appears across long façades, heavy walls and carved doorways, giving the historic centre a consistent material character.

The stone is also a surface for decoration. Baroque façades carry deep relief, floral details, geometric borders and local imagery, while entrances and galleries use arches. In the casonas, vaulted roofs and interior courtyards connect domestic architecture with the larger urban fabric.

Colonial forms and native craftsmanship

Arequipa’s historic centre took shape during the Spanish colonial period, with early buildings dating from the seventeenth century. European architectural forms appear in churches, civic buildings and residences, while Indigenous and Criollo masons developed the city’s carved volcanic-stone vocabulary.

Robust masonry, arcades, vaults and open courtyards are recurring features. The result is not a collection of isolated monuments, but an urban ensemble in which streets, religious buildings and townhouses share materials and decorative habits.

From colonial settlement to World Heritage city

The official World Heritage name is Historical Centre of the City of Arequipa. UNESCO inscribed the cultural site in 2000, recognising its ornamented architecture and the integration of European and native characteristics.

The protected historic centre includes religious, civic and domestic buildings. Among its prominent landmarks are the Basilica Cathedral of Arequipa, Santa Catalina Monastery, the Church of La Compañía and the courtyards of colonial casonas. World Heritage designation places the city’s stone architecture within a wider history of colonial settlement and regional cultural exchange.

Public squares and arcaded streets provide the clearest view of the centre’s proportions. In the Plaza de Armas, the cathedral façades and surrounding arcades frame an urban space whose details range from monumental stonework to small carved elements above doorways.
