The Terre-Nègre lighthouse is a landmark forming a cylindrical tower a little over 26 meters high.
Located on the tip of Terre-Nègre, in the commune of Saint-Palais-sur-Mer, in Charente-Maritime, it is intended to mark the southern pass of the Gironde estuary and to signal the presence of a dangerous sandbank, the "Anglais bar".
This building forms a tower-column 3.16 meters in diameter and 26.60 meters high. A spiral staircase with a central core of 143 steps leads to a summit platform equipped with a directional light. The tower is painted in two different colors to make it more visible: the upper part is red, the lower part is white.
The base of the lighthouse is hidden by a building that once served as the keeper's accommodation.
The installation of a beacon at this location was considered as early as 1763. De Kearney took over the beaconing plan four years later. Construction work on the tower began in 1770 and was completed in 1773, probably under the supervision of the Bordeaux engineer Claude Tardy.
In 1807, the tower was raised. However, this work was considered insufficient by some of the estuary's navigators. In 1834, sailors from the nearby port of Royan sent a request to the Ministry of the Navy to study the possibility of equipping the tower with a light. However, this request was postponed the following year due to lack of sufficient funds.
A new request from sailors prompted the lighthouse commission to experiment with a first light in 1836. Finally, on October 15, 1838, a fixed white 4th order light was permanently installed. The latter was replaced in 1856 by a fixed white light of the 4th order of a small dioptric model with a reinforced sector of the 5th order catoptric. It was equipped with new lights in 1899 and 1904. In 1939, it was electrified.
During the German occupation, the lighthouse served as an observatory for the soldiers of the Wehrmacht. Damaged during the fighting of 1945 (presence of breaches at the top of the tower), it was restored in the immediate post-war period.
In March 1947, the lighthouse was operational again. A light with 3 occultations — changing every 12 seconds — was installed. Its colors are white, red and green. Its current range is 18 miles.
Listed as a Historic Monument since 2011, the lighthouse is not open to visitors. However, it can be admired from the outside and a pretty passage provides direct access to the coastal path.
