Mãe Luiza Lighthouse, Lighthouse in Mãe Luíza, Natal, Brazil

Mãe Luiza Lighthouse is a white concrete tower on Natal's coast that rises approximately 37 meters above the ground. Its beacon reaches about 87 meters in height and can be seen from far out at sea.

A small lighthouse, the farolete dos Reis Magos, was already operating in 1858 at the Forte dos Reis Magos at the mouth of the Potengi. In 1872 it was replaced by a 12-metre metal tower. After the port of Natal opened in 1922 and maritime traffic grew, the present tower was built from 1949 to 1951 and inaugurated on 15 August 1951, replacing the old light.

The lighthouse bears the name of a local midwife who helped families in the neighborhood during the mid-20th century. This choice reflects how the community honors those who served it most closely.

Public visits take place only on Sunday afternoons; the rest of the week the tower is closed. Access to the top is by an internal staircase of 151 steps, so allow time for the climb. The site lies in the Mãe Luíza neighbourhood, within the urban area of Natal.

The beacon emits a distinctive pattern of five white flashes every 25 seconds, helping ships in the South Atlantic identify it from a distance. This specific signal makes it recognizable compared to other lighthouses in the area.
