After Manoel Joaquim Ferreira Netto immigrated from Portugal to Brazil in 1838, he became a real estate baron in Santos. In 1860, he began converting an old salt warehouse into his plush residence. Casa da Frontaria Azulejada seems delightfully out of context in the city. The former mansion has Mudéjar elements covered with seven thousand Portuguese porcelain tiles. The building was later repurposed as a warehouse, hotel and fertilizer depot. After it was abandoned in 1986 and became decrepit, it was purchased by the city and restored. Inside Tiled Frontier House is an event venue named Cultural Space Frontario Azulejada.
