History

On 8 January 1856, a dispatch determined the need for a lighthouse along the coastal area at the mouth of the Ria de Aveiro; the Director das Obras Públicas do Distrito de Aveiro (Aveiro District Director of Public Works), in accordance with the Porto captaincy and Director Maquinista de Faróis (Lighthouse Mechanical Director), indicated the appropriate location for a new lighthouse. The authorities had rejected the idea of reusing the signal tower from the Fort of Barra in order to construct the Barra light in 1858. On 14 October 1870, by dispatch a general illumination plan was approved for the coast, elaborated by counsel Franciso Maria Pereira da Silva. The plan for the lighthouse was approved in 1879, that included an octagonal tower of 55 metres (180 ft) high.

The construction of the lighthouse occurred between 1879 and 1893, after alterations to the original project. This lighthouse replaced the services of the Hermitage of Senhora das Areias which, from the writings of friar Agostinho de Santa Maria:

...for navigators it served as lighthouse as lookout and fixed star, that, the dangers of big storms and tempests, warned those that could shipwreck, to escape from that inhuman wave, which subverts ships...

The build was initially under the direction of engineer Silvério Pereira da Silva and later by engineer José Maria de Mello e Matos, envisioning a budget of 51 contos de réis and an elevator that would eliminate the need for a 228 step winding staircase. The first beacon was an incandescent petrol lamp and horn combination and began to operating on 15 October 1893. The lighthouse would later be supported by a first-order lamp, with four clarions, oscillating at 2.5 seconds and with a 1.5 eclipse, and a 9.5 second interval, that allowed it to reach 20 nautical miles (37 km). In addition, the Holmes fog signal was a installed at the same time to provide a warning in the fog.

By 1929, the lighthouse was repaired following the several faults and failures that caused by oscillations in the tower. Public works occurred this year, that included the isolation of the main structure with tiled walls and the installation of 14 cement columns to reinforce the building. In 1935, the signal horn was moved into the interior of the building following its predecessor being swept away during a storm, and a year later, the building was electrified with the installation of a generator.

In 1947, the beacon was substituted by the current installation, a small third-order Fresnel lens beacon with panels, that included four white flashes that repeated every 13 seconds, and with a 23 nautical miles (43 km) range.

In 1950, the lighthouse was added to the public electrical network, while the the 3000W lamp was replaced by a 1000W lamp.

A study was elaborated in 1954 by the Direcção-Geral dos Serviços de Urbanização (Directorate-General Urban Services), through its Serviços de Melhoramentos Urbanos (Urban Improvement Services), to examine the potential of improving the sites position along the coast leading to the construction of a sea wall to protect the structure. Between 1958 and 1959, the DGEMN began building repairs, under the auspice of the Serviços de Construção e Conservação (Construction and Conservation Services).

In the following four years a elevator was built to provide access to the beacon, and the light was automated in 1990.

Architecture

Barra Beach and Lighthouse, overview

The lighthouse is situated along the southern mouth of the Vouga River, in the village of Barra, along the Avenida Fernão de Magalhães and Avenida João Corte Real. It is situated in an isolated place 66 metres (217 ft) along the coastal beach, with the lighthouse providing views of the sea, the Ria, the beaches of Barra and Costa Nova, as well as the towns of Gafanhas, São Jacinto and city of Aveiro.

The lighthouse tower is 62 metres (203 ft) high, with the beacon extending to 66 metres (217 ft) height and a range of 23 nautical miles (43 km). The round stone tower rises from a two-story lighthouse keeper's house, supported by a spiral staircase of 271 stone steps (followed by an additional 20 metal steps), while the elevator rises through the middle of the spiral stairway.
