Santa Catalina in Arequipa: A Walled City of Nuns in the Andes
In the centre of Arequipa, only a few blocks from the Plaza de Armas, a high blind wall of pale volcanic stone runs along an entire city block. Behind it lies not a single building but a complete miniature town: the Monasterio de Santa Catalina de Siena, a Dominican convent founded in 1579 and sealed off from the outside world for almost four hundred years. Streets with Spanish names, painted plazas, a laundry, kitchens, cells the size of small houses - all of it stayed hidden until the gates finally opened to visitors in 1970. Today it is the most famous monument in southern Peru and one of the most extraordinary religious complexes anywhere in the Americas.
A convent born of colonial wealth
Santa Catalina was founded in 1579, barely four decades after the Spanish founding of Arequipa itself. The driving force was a rich widow, María de Guzmán, who endowed the new convent and entered it herself as one of its first religious women. The house was dedicated to Saint Catherine of Siena, the great Dominican mystic, and it followed the Dominican rule from the beginning.
From the start the monastery reflected the social order of the Spanish colonial world. It received the daughters of wealthy Spanish and Creole families, and custom held that a family of standing would dedicate one daughter to religious life. Entry was far from free: families paid a substantial dowry, and the richest novices arrived with fine porcelain, silk curtains, servants and furniture. The result was a paradox that still fascinates visitors - an enclosed house of prayer that was, at the same time, one of the wealthiest addresses in the city.
A city within a city
What makes Santa Catalina unique is its sheer urban scale. The complex covers roughly twenty thousand square metres - about two hectares in the middle of the historic centre - and it is organised not like a single cloister but like a town. Real streets run between the buildings, and they carry the names of Spanish cities: Calle Córdova, Calle Toledo, Calle Sevilla, Calle Granada, Calle Burgos, Calle Málaga. There are squares, fountains, gardens and passageways, along with communal spaces such as the great kitchen and an open-air laundry where water was channelled through halved earthenware jars.
At its height the enclosure functioned as a self-contained world. Several hundred women lived inside the walls - nuns, novices and the servants who attended them - and everything a small community needed existed within the precinct. A wall higher than the surrounding rooftops separated this world from the noise of Arequipa, and the nuns who entered as young women generally never left again.
Sillar: building with the volcano
Arequipa is called the White City because of sillar, the pale volcanic stone quarried near the city, and Santa Catalina is one of the great works in this material. Sillar is light, porous and easy to carve, and it gives the monastery its thick walls, its barrel vaults and its rounded buttresses. The architecture is a mudéjar-inflected colonial style adapted to a violent landscape: Arequipa sits in the shadow of the volcano El Misti and in one of the most seismically active regions of South America.
Earthquakes have shaped the monastery as much as any architect. Over the centuries, repeated tremors brought down vaults and cracked walls, and each reconstruction added another layer to the complex. The low, massive, organic look of the buildings - few straight lines, walls that lean into each other, small enclosed volumes rather than grand halls - is in part a survival strategy. What could not resist the earth was rebuilt, again and again, in the same white stone.
Colour behind the walls
Visitors expecting monastic austerity are surprised by the colour. Whole streets and courtyards of Santa Catalina are painted in an intense cobalt blue, others in a deep ochre red, and the contrast of these saturated walls against the white sillar and the fierce Andean light has made the monastery one of the most photographed places in Peru. The Claustro de los Naranjos, the cloister of the orange trees, combines blue walls with green trees and painted crosses; the larger Claustro Mayor is lined with mural decoration; and the small Plaza Zocodober, whose name recalls the market squares of Moorish Spain, served as a meeting point where nuns could exchange goods.
The living quarters tell their own story. Rather than identical cells along a corridor, many nuns inhabited what are effectively small private houses, with a sleeping alcove, a sitting room and a private kitchen. Walking from one to the next, you can read the social hierarchy of the colonial convent directly in the architecture.
Reform and the end of private wealth
The comfortable arrangements inside Santa Catalina eventually drew the attention of Rome. In 1871 Pope Pius IX sent a strict Dominican reformer, Sister Josefa Cadena, to bring the monastery back to a more rigorous observance. The reform changed life inside the walls profoundly: private wealth was given up, the richer nuns freed their servants and enslaved women - who could choose to leave or to remain as members of the community - and communal life replaced the semi-independent households of earlier centuries.
The monastery had already produced figures of deep spirituality long before the reform. The most celebrated is Sor Ana de los Ángeles Monteagudo, a nun of the seventeenth century who served the community as prioress and became renowned for her holiness. She was beatified by Pope John Paul II in 1985, during his visit to Arequipa, and her memory is kept alive both in the monastery and in the devotion of the city.
The opening of 1970
For almost four centuries Santa Catalina remained closed to outsiders. The turning point came in the twentieth century, when powerful earthquakes in 1958 and 1960 damaged the complex and the community faced the cost of repairs and of modernising the enclosure with electricity and running water. The solution was radical: in August 1970 the greater part of the monastery was opened to the public as a monument, while the nuns withdrew to a reserved section in one corner of the complex.
The opening revealed a time capsule. Because the enclosure had changed so little, visitors could suddenly walk through a colonial townscape preserved with its kitchens, furniture and painted walls intact. A small community of Dominican nuns continues to live in the closed quarter to this day, so the monastery is not only a museum but a living religious house. In 2000, UNESCO inscribed the historic centre of Arequipa on the World Heritage List, with Santa Catalina as its most remarkable single monument.
Visiting the White City's hidden town
Santa Catalina rewards slow exploration. Most visitors spend a couple of hours wandering the painted streets, but the complex is large enough to get pleasantly lost in: the route leads through cloisters, cells, the great kitchen with its blackened vault, the laundry court and a picture gallery with religious paintings of the colonial Andes, many in the tradition of the Cusco school. Evening visits, when the streets are lit by candles and lanterns on certain days, show the monastery in a completely different mood.
The monastery sits at more than two thousand three hundred metres above sea level, so it is worth taking the altitude gently. Combine the visit with the sillar façades of the Plaza de Armas and the viewpoints towards El Misti, and Arequipa's nickname of the White City explains itself within a single afternoon.
