The fort's name translates to 'Fortress of the Magi' in honor of the date of its foundation.
The structure was designed using a 'trace italienne' star-shaped pattern to maximize defensive fields of fire.
The fort is built on a sandstone reef that remains exposed at low tide, creating a natural sea bridge.
During the Dutch occupation, the fort served as the administrative capital of New Holland in the region.
The walls were constructed using 'pedra e cal' (stone and lime), mixed with whale oil, a common colonial construction technique.
It is the oldest building in Natal and the point from which the city's urban expansion originated.
The internal chapel features a stone floor covering the original cistern used to store rainwater.
The site houses several bronze cannons dating back to the Portuguese colonial era.
The fort is situated at the exact point where the Potengi River meets the Atlantic Ocean.
Archaeological excavations at the site have unearthed 17th-century Dutch ceramic fragments.
Fortaleza dos Reis Magos is a star-shaped maritime fort founded on January 6, 1599, the Day of the Three Wise Men. Located on a limestone reef at the mouth of the Potengi River, it served as the defensive cornerstone for the colonial occupation of Rio Grande do Norte. The structure features a unique geometric layout influenced by Italian military engineering of the period. Its interior holds historical cannons, a chapel, and living quarters that reflect 17th-century Portuguese military life. The fort was occupied by the Dutch between 1633 and 1654, during which it was renamed Castelo Keulen. It is built directly upon the reef rock, which serves as its natural foundation. The site is a National Historic Monument under the protection of the National Institute of Historic and Artistic Heritage (IPHAN). The fort has undergone multiple restoration phases to maintain its structural integrity against salt air erosion.

Check the tide charts before visiting, as access across the sandbank can become challenging during high tide.
Bring sun protection, as the site has very little natural shade or cover from the equatorial sun.
Wear comfortable, flat-soled shoes with good grip, as the reef-based path and historic floors are uneven.
Do not attempt to walk across the reef during a rapidly rising tide. Avoid visiting in flip-flops due to the sharp, uneven nature of the limestone reef path.
Closed on Mondays for maintenance and staff rest.
Maintain respectful behavior within the chapel area; avoid touching or leaning on the historical cannons.
