This institution was a 'preventório' - a place for children of parents with leprosy.

In December 1936, the Directors of the Federação das Sociedades de Assistencia aos Lazaros formed the Campanha da Solidariedade (Campaign of Solidarity), with the aim to obtain funding for the construction of a 'preventório' in Santa Catarina.
