Lowestoft Lighthouse

Lowestoft Lighthouse was built by Trinity House in 1874, the latest in a series of towers established in 1609 to safeguard vessels along this dangerous stretch of the East coast

In 1609 Trinity House responded to petitions from shipowners and merchants who had lost cargoes and vessels on the sandbanks and shoals around the East coast. The proposal was to erect two towers—high and low lights, or ‘leading lights’—“for the direction of ships which crept by night in the dangerous passage betwixt Lowestoft and Winterton.”

Two lighthouses were established on the low lying foreshore known as Lowestoft-ness, the illuminant being tallow candles. When the two lights were in line they led vessels through the Stamford Channel, an inshore passage used by small vessels which no longer exists.

The lighthouses were rebuilt in 1628 and again in 1676 when the rear light was erected upon the cliff as the light was no longer solely used by vessels feeling their way along the coast, but also by those approaching from far out to sea. The new high lighthouse—which cost £300—was a substantial building of brick and stone and in order to improve the light the candles were replaced by a coal fire.

In 1706, owing to encroachment by the sea, the low light was discontinued. For years afterwards the shipmasters complained of the difficulty in navigating the Stamford Channel during the night time, and so in 1730 it was re-established as an oil light, burning whale oil in an open flame lamp. The new low light was designed to be moveable on account of either the encroachment of the sea or a change in the direction of the Stamford Channel.

In 1777 Trinity House experimented with reflector lights at Lowestoft. The coal fire in the high light was replaced by a new glass lantern 7ft high and 6ft in diameter. Inside this was erected a large cylinder covered with 4,000 small mirrors. These reflected the light from oil lamps arranged in a circle around them. The 'spangle light' as it was known was said to have a range of 20 miles, and was welcomed by all who saw it. However, the development of lighthouse optics at this period was making vast strides and by 1796 the spangle light had been abandoned and Argand lamps and silvered parabolic reflectors were installed at a cost of £1,000.

Following experiments with electric lighting at South Foreland Lighthouse, in 1870 the decision was taken to electrify the Lowestoft High Light. The existing tower was not considered strong enough to take the weight of the new equipment and a new tower which still stands today was built at a cost of £2,350. However before the tower was ready to receive the electrical apparatus paraffin oil became available as an illuminant, and it immediately proved itself to be so economical and efficient that it was adopted for use in the new lighthouse in preference to electricity. At the same time a new optical system was fitted having a revolving lens, and the light, which up to then had always been fixed, was made to flash at half-minute intervals. The rebuilding was completed in 1874.

By the early 1920s the low light had ceased to fulfil any useful function due to the disappearance of the Stamford Channel and was finally extinguished in August 1923. The high light was automated in 1975 and modernised in early 1997.

The lighthouse is now monitored and controlled from Trinity House’s Planning Centre in Harwich, Essex.
