Fortress of Our Lady of Remedies stands prominently on Fernando de Noronha, a remote Atlantic island, representing the most significant fortification in the island's 18th-century Portuguese defensive system. Construction began in 1737 and took 41 years to complete, with the fortress positioned on a hill between Santo António Bay and Cachorro Beach. Built atop a former Dutch fort, it features impressive 2.9-meter-high walls with 3.5-meter-thick bases and once housed seven cannon batteries totaling 27 guns, many of which remain visible today. Expanded and restored in 1859, the fortress served dual purposes as both a coastal defense and as a political prisoner detention facility. The well-preserved structure continues to demonstrate sophisticated military engineering adapted to the island's strategic location in the Atlantic Ocean.
