History

On 2 March 1882, the Comissão dos Faróis e Balizas (Commission on Lighthouses and Beacons) released the first plans for the installation of a lighthouse in Ponta das Contendas, equipped with a second-order lantern, that would illuminate a 240º focal range with 4 clarions (three white and one red). A year later, there was a determination that Ponta de São Jorge would be a better candidate.

By 1902 the lighthouse had not yet been built. A new commission judged that Ponta de São Jorge was too obscure, and judged that a more convenient site would be Ponta das Contendas. The revised project substituted the second-order lantern for a fifth-order light, with six clarions.

 (equivalent to 6 Euros). Finally, in 1930, the construction of the lighthouse began, under the direction of António Tomaz. On 1 February 1934, the completed lighthouse was inaugurated, with the installed third-order lamp (with a 500 millimetre focal distance). At the inauguration:
After all the preparations and at the arrival of the hour, the lighthouse chief lit and put into function the optics, His Excellency the Captain of the Port gave a speech to the people.

The mechanism allowed for a fifteen second beacon interval, using a incandescent bulb powered by petroleum gas, resulting in a visible range of 32 miles (51.5 km).

On 1 June 1958, the beacon was electrified. The new electric bulb increased the light's visible range to 38 miles (61.2 km).

In 1964, a paved road to the lighthouse and connections to the public water system were finally completed.

The lighthouse began to operate with a 1000 watt/120 volt lamp in 1983, reducing its range to 26 miles (41.8 km), or 23 nautical miles. This was followed in 1985 by the introduction of a two-sector red lamp, with the objective of assisting navigation in the most dangerous sectors, including those near the islets of Fradinhos.

In 1998, the connection to the public electrical network was completed.

On 1 February 2009, the lighthouse celebrated 75 years of operation on the Contendas Point. Presiding over the ceremony were representatives of the Portuguese and Azorean governments, the Maritime Department, and the Captain of the Port Authority of Angra do Heroísmo

Architecture

Located along the maritime coast, in the south-east corner of the island of Terceira, called Ponta das Contendas, it is situated in an elevated zone, resulting in a focal point that is 54 metres above sea level. Although protected by a wall, the lighthouse (ARLHS AZO-007; PT-745; Admiralty D2664; NGA 23532) is on the edge of a high cliff, and accessible only from the Estrada 509, alongside several agricultural fields.

Its plan is composed of four inter-connected rectangular rooms connected by a central body (taking the form of a "H"), on which the main 13 metre-high prismatic white tower is surmounted by a red cupola
