Praia da Armação, Beach strip in southern Florianópolis, Brazil.

Praia da Armação is a curved beach on the southern tip of Florianópolis, Brazil, flanked by rocky outcrops at each end and crossed by a small river outlet near the shore. The beach has open sections where waves come in more strongly and sheltered spots with calmer water closer to the river mouth.

The name comes from a whaling station set up in the 18th century to produce whale oil used for lighting streets in the city. Operations continued well into the 20th century, and traces of that period can still be found in the village layout and architecture.

The Sant'Anna Church stands at the heart of the village and draws locals during festivals and everyday life. The surrounding neighborhood still feels like a fishing community, with boats on the sand and nets drying near the shore.

The calmer water near the river mouth is a good starting point for swimming, while the open sections of the beach are better suited for surfing. It is worth checking sea conditions before entering the water, as currents can shift depending on the season.

The spot where whalers once gathered is now a bar that welcomes visitors in a traditional setting, as noted in the French-language source. The Sant'Anna Church, built in 1772, was where harpooners confessed and heard mass before setting out; the priest then went down to the beach to bless the boats.
