History

The small lighthouse was constructed in November 1910, with a sixth order diotropic^{[check spelling]} light, providing a fixed white light, that ranged to 10 miles (16 km), supported by acetylene gas.[2]

In 1955, construction began on a modernization of the light.[2] By May 1956, the new light was inaugurated, this time using a fourth-order dioptric light, in groups of double clarions, with a 15 miles (24 km) range.[2]

Its power source was changed in February 1987, to photovoltaic panels, and converted to a solar panel-battery reserve system by the first decade of the 21st century.[2]

Architecture

This light is located on the clifftop promontory of Ponta Negra, on the southern coast of Corvo (west of the port of Boqueirão) alongside the traditional windmills; it is at the edge of the Caminho dos Moinhos near the westernmost windmill of the group.[2]

Originally the illuminating tower was an ironwork structure 6 metres (20 ft) high, with small cabana-like metal annex, painted in red.[2] The modern building consists of a beacon mounted to a hexagonal tower, constructed of reinforced concrete.[2] The small tower is 3 metres (9.8 ft) high, and the current light is 23 metres (75 ft) above sea level, providing a range of sight to 6 miles (9.7 km), using a simple white beacon with five second interval.[2]
