The Fort of Santa Cruz stands on the small island of Anhatomirim, at the northern entrance to the channel around Santa Catarina Island. The island belongs to the neighboring municipality of Governador Celso Ramos, but the visit is one of the classic trips from Florianópolis.

History

Designed by Brigadier José da Silva Paes, the first governor of the Captaincy of Santa Catarina, Anhatomirim was the first corner of the North Bay defensive triangle, alongside the forts of São José da Ponta Grossa and Santo Antônio de Ratones, begun around 1740, according to Wikipedia. The name comes from the Tupi language and means “little island of the devil”.

How to visit

  • Access by boat only. UFSC states that it does not provide transport: it is offered by local marine transport companies, such as the schooners that leave from the north of the island.
  • Opening hours: UFSC lists Tuesday to Sunday, 8:30 a.m. to 6:30 p.m., including public holidays, with last entry at 6 p.m. (checked in October 2026).
  • Visitor fee: charged by UFSC for the upkeep of the monument. Check the amount on the official website.
