The Spanish conquerors not only conquered Peru militarily, but also sought to convert the indigenous populations to Christianity. Indigenous Andean religious beliefs and practices persisted, which the Catholic Church sought to suppress. Many churches were built in the colonial period, the visible manifestation of Catholicism. Some convents were also built on Inca sites. For example, in 1605, some Dominican nuns built the Convent of Santa Catalina in Cuzco atop the site of the "acllahuasi", once home to virginal young women dedicated to serving the ruling Inca. Another convent, the Convent of Santa Clara, was one of the first institutions the conquistadores of Cuzco built for "Indian nobles", the daughters of the indigenous elite whose collaboration made Spain's indirect rule over the Andes possible. At Santa Clara, Inca nobles were to be "raised Christian and to receive 'buenas costumbres' (literally, good customs or manners), shorthand for an education in Spanishness", which included knowledge, stitchery, and literacy. After graduating from this course in Spanish culture, charges were free to profess vows or leave the convent. Miscegenation was not an issue among Spaniards. Many prominent Spanish men lived with elite Inca women, only to marry Spanish women later in life and marry off their Andean partners to less prominent Spaniards.
