The Sant'Anna Church, built by the Armação fishing company, is part of the beach's history. It was from there that whale harpooners and crewmen confessed and attended the mass before going fishing. Next, the priest would go down to the beach to bless the boats that would sail out to sea. Today, the boats leave there for Ilha do Campeche, one of the most visited islands around Florianópolis. It is also in Armação that one finds one of the most important archaeological sites of the State of Santa Catarina. In the winter of 2010 a significant portion of the beach disappeared due to erosion. With financial aid from the Brazilian federal government, tons of large rocks were dumped on the beach to prevent houses from destruction.
