"Pedro de Osma" likely honors Peruvian art collector and politician Don Pedro de Osma y Pardo, whose mansion in Barranco now houses a notable art museum specializing in colonial art. The "IEI N° 10" denotes an "Institución Educativa Inicial N° 10," or Initial Educational Institution No. 10. In Peru, "Initial Education" (Educación Inicial) refers to schooling for children aged 0 to 5, similar to preschool or kindergarten in other countries. The colorful murals are typical of children's educational facilities. The large water tanks on the roof are common in many Peruvian buildings, often used to store water due to intermittent supply or as a reserve.
