The Monasterio de Santa Catalina, built in 1580 is an old convent converted into a tourist attraction in Arequipa. It features Mudejar style architecture and very vivid wall colors. This is an extract taken from Wikipedia about the history of the place.
“The founder of the monastery was a rich widow, Maria de Guzman. The tradition of the time indicated that the second son or daughter of a family would enter religious service, and the convent accepted only women from high-class Spanish families. Each nun at Santa Catalina had between one and four servants or slaves, and the nuns invited musicians to perform in the convent, gave parties and generally lived a lavish lifestyle. Each family paid a dowry at their daughter’s entrance to the convent, and the dowry owed to gain the highest status, indicated by wearing a black veil, was 2,400 silver coins, equivalent to US$50,000 today. The nuns were also required to bring 25 listed items, including a statue, a painting, a lamp and clothes. The wealthiest nuns may have brought fine English china and silk curtains and rugs. Although it was possible for poorer nuns to enter the convent without paying a dowry, it can be seen from the cells that most of the nuns were very wealthy.”
