Frontaria Azulejada House, historic house in Santos, Brazil

The Frontaria Azulejada House is a neoclassical residence in Santos featuring a facade decorated with blue and white tiles in raised relief. The building has balanced proportions, symmetrical windows with shutters, and was originally designed to serve as both a home and warehouse for a Portuguese trader.

Built in 1865 by Portuguese commander Manoel Joaquim Ferreira Netto as his residence and warehouse, the house later became the Hotel Guanabara between the 1940s and 1960s. After serving as a chemical fertilizer depot, it was listed by SPHAN in 1973, expropriated by the municipality in 1986, and restored from 1992.

The name Frontaria Azulejada refers to the tiled front of the house: the facade was covered with tiles imported from Portugal, probably after the death of Manoel Joaquim Ferreira Netto, by his partner Luiz Guimarães. Since 2007 the building has served as the Espaço Cultural Frontaria Azulejada, run by the Fundação Arquivo e Memória de Santos for exhibitions, charity events and cultural performances.

The house stands on Rua do Comércio in Santos' historic centre. Its interior is not open to visitors, so the tiled façade and portal are seen from the street. Since 2007 the building has functioned as the Espaço Cultural Frontaria Azulejada, hosting exhibitions and cultural events.

The facade's tiles were probably applied after the death of Manoel Joaquim Ferreira Netto by his partner Luiz Guimarães, not at the time of construction. During the 1992 restoration, the atelier of artist Luís Sarasá restored or replaced them, producing 7,000 new pieces. The interior was left with a rustic appearance.
