Tynemouth lighthouse from South Shields pier.
A lighthouse had built on the old North Pier (first lit in 1895, it displayed three lights mounted vertically: green over white over red, with a range of 7 nautical miles (13 km; 8.1 mi)); however, when the pier had to be rebuilt to a new design, an entirely new lighthouse was required. The work was undertaken by Trinity House, beginning in 1903; the lighthouse was finished before the pier itself, and was first lit on 15 January 1908.The revolving optic, manufactured by Barbier, Bénard, et Turenne, displayed a flash three times every ten seconds; it remains in use today. The light source was an incandescent oil vapour lamp, which (together with the optic) produced a 70,000 candle-power light with a range of 15 nautical miles (28 km; 17 mi). The lighthouse was also equipped with a reed fog signal, powered by compressed air, which was mounted ‘on the cupola’; it sounded one long blast every ten seconds. It was manned by four keepers, with two on duty at any one time. In September 1961 a new, more powerful electric light was installed by the Tyne Improvement Commissioners (powered from the mains). Then in 1967 the lighthouse (by then staffed by six keepers on rotation) was automated; a diesel generator was installed along with an electric foghorn.
Before the pier was built, a lighthouse stood within the grounds of Tynemouth Priory and Castle. It was demolished in 1898. It stood on the site of the now-disused Coastguard Station.
