A hill in Paraisopolis, Sao Paulo's second-largest favela, showcases the work of Estevao Silva da Conceicao, who has spent four decades building a unique castle that has earned him the nickname "the Brazilian Gaudi." "In the beginning, I faced a lot of criticism," says Silva da Conceicao. The 67-year-old former gardener and mason has created a striking structure on a steep block, featuring colorful broken tiles, porcelain plates, and brown stones on its facade. "I poured my sweat into this project; I worked hard on it, so I can truly say it's the work of my life," he adds. IMAGES AND SOUNDBITES
