Souter Lighthouse

The lighthouse is located on Lizard Point, but takes its name from Souter Point, which is located a mile to the south. This was the intended site for the lighthouse, but it was felt that Lizard Point offered better visibility, as the cliffs there are higher, so the lighthouse was built there instead. The Souter Lighthouse name was retained in order to avoid confusion with the then recently built Lizard Lighthouse in Cornwall.

Souter Lighthouse is approximately three miles south of the mouth of the River Tyne. Some four miles or so to the north of the mouth of the Tyne is a sister Victorian lighthouse, St Mary's Lighthouse, on St Mary's Island. It has also been decommissioned, and is open to visitors. St Mary's Lighthouse can be seen with the naked eye from the top of Souter Lighthouse.Personal observation

The lighthouse was a much-needed aid to navigation due to the number of wrecks on the dangerous reefs of Whitburn Steel{{cite news | title = Newcastle Courant | date = 18 June 1869 | pages = 6 | quote = a new lighthouse to be erected on Souter Point...It will erected to prevent wrecks from occurring, if possible, on Whitburn Steel, of which there have been so many complaints within recent years.}} which lay directly under the water in the surrounding area. In one year alone – 1860 – there were 20 shipwrecks. This contributed to making this coastline the most dangerous in the country, with an average of around 44 shipwrecks per every mile of coastline.{{Cn|date=July 2022}}

The lighthouse and associated buildings were designed for Trinity House by their Chief Engineer, James Douglass; its construction was supervised by on-site engineer Henry Norris.{{cite news | title = Shields Gazette and Daily Telegraph | date = 9 September 1870 | pages = 3 | quote = the works are being pushed rapidly forward under the supervision of Mr H.

Most of the people in Shields hardly ever saw a Sunderland paper in their lives, yet the Shields builders were virtually shut out from competing for a lighthouse within the limits of their own Poor-Law Union, so far as publicity of the fact of tenders being wanted was concerned. Communications were accordingly made from this office on the subject; the advertisement appeared in the Gazette, and a South Shields contractor ultimately got the job. }} The foundation stone was ceremonially laid by Admiral Collinson's sister on 9 June 1869.{{cite news | title = Shields Gazette and Daily Telegraph | date = 9 June 1869 | pages = 9 | quote = The foundation-stone of the lighthouse at Souter Point was laid yesterday afternoon by Mrs Blain (sister to Admiral Collinson) in the presence of the committee of the Elder Brethren of the Trinity House, London, Admiral Collinson, Captain Nesbitt, Captain Webb, Mr G.

Robert [sic] Norris is the superintendent of the works, and Mr James Todd is the contractor. }} Building works were completed in 1870, and the lighthouse entered service in January the following year. After completing this project Douglass and Norris moved on to the building of Hartland Point Lighthouse in Devon.

Carbon arc lights for lighthouses were pioneered by Professor Frederick Hale Holmes, with experiments carried out in 1857–60 at Blackwall and at South Foreland Lighthouse (as described in a lecture {{cite news | title = Newcastle Courant | date = 30 March 1860 | pages = 3 | quote = MAGNETO-ELECTRIC LIGHT FOR LIGHTHOUSES - Professor Faraday, in a lecture delivered at the Royal Institution, says: "By means of a magnet, and of motion, we can get the some kind of electricity as from the battery; and, under the authority of the Trinity House, Professor Holmes has been occupied in introducing the magneto-electric light in the lighthouse at the North [sic] Foreland...For the last six months the North [sic] Foreland has been shining by means of this electric light beyond all comparison better than its former light.

The carbon arc lamp at Souter was placed within a lens array consisting of a third-order fixed catadioptric optic surrounded by a revolving assembly of eight vertical condensing-prisms which produced one bright flash every thirty seconds.{{cite book |last1=Elliot |first1=George H. |title=European Light-House Systems |date=1875 |publisher=Lockwood & co. |location=London |pages=120–127 |url=http://access.bl.uk/item/pdf/lsidyv38f8413f |access-date=10 March 2019 |archive-date=29 October 2020 |archive-url=https://web.archive.org/web/20201029210746/http://access.bl.uk/item/pdf/lsidyv38f8413f |url-status=dead }} Its 800,000 candle power light could be seen for up to 26 miles.

In addition to the main light a red/white sector light shone from a window in the tower below the lantern, to highlight hazards to the south in Sunderland Bay (namely Hendon Rock and the White Stones); it was powered using light diverted (through a set of mirrors and lenses) from the landward side of the main arc lamp.{{cite web|title=Trinity House History page, quoting Newcastle Courant 12 Jan. 1871|url=https://trinityhousehistory.wordpress.com/tag/souter-point/}}

}} during those years. In normal operation only one generator was used, but in conditions of poor visibility both were connected to the lamp to provide a brighter light. The generators were driven by one of a pair of J. Whitworth & co. 5 nhp 'Allen' condensing steam engines.{{cite journal |last1=Douglass |first1=James Nicholas |title=The Electric Light applied to Lighthouse Illumination |journal=Minutes of Proceedings of the Institution of Civil Engineers |date=25 March 1879 |volume=LVII |issue=1,639 |pages=82–87}} (Prior to being installed at Souter, the engines and generators were exhibited by Trinity House at the Paris Exposition of 1867.) The engines were worked alternately: one week on, one week off. Located in the engine-house, they also drove an air-pump to feed the pressure tank of a foghorn.

In December 1891 the lighthouse tower was painted with a broad red band, to make it more conspicuous during the day.[https://www.thegazette.co.uk/London/issue/26237/page/7213 London Gazette, Issue 26237, Page 7213, 29 December 1891.]

Holmes also designed a reed fog signal for the new lighthouse, sounded from a separate foghorn house (east of the tower) through a pair of vertical trumpets (angled north-east and south-east, facing out to sea).{{cite journal |title=Fog Signals |journal=The Nautical Magazine |date=November 1871 |pages=769–770}}[https://twsitelines.info/SMR/2489 photo c.1900] It sounded one blast every 45 seconds. Compressed air for the foghorn was piped underground from the engine room, on the other side of the lighthouse, where the air compressor was driven by a common drive shaft from the engines powering the magnetos.{{cite book |last1=Renton |first1=Alan |title=Lost Sounds: The Story of Coast Fog Signals |date=2001 |publisher=Whittles |location=Caithness, Scotland}}

A more powerful siren fog signal replaced the reeds in February 1879;{{cite journal |title=Fog Signals |journal=Parliamentary Papers, Volume LXIV |date=1 August 1879 |volume=23 |issue=337 |pages=2–4}} it sounded one blast every minute.[https://www.thegazette.co.uk/London/issue/24739/page/4214 London Gazette, Issue 24739, Page 4214, 1 July 1879.] It required an additional and more powerful engine, which was installed in the engine room to drive the compressor for the new signal.

In 1914 the pioneering electric light at Souter was replaced with the latest type of incandescent oil lamps (i.e. paraffin vapour burners). At the same time Chance Brothers provided a new, much larger lens system: a bi-form first-order catadioptric revolving optic (a bi-form lens is double-height, containing two lamps, one above the other). At the same time a new lantern was provided, to accommodate the taller optic. Red shades were placed around the lamps, within the lenses, so that the light now flashed red, once every 5 seconds.{{cite book |title=Index to Notices to Mariners 1919 |date=1920 |publisher=U.S. Navy Hydrographic Office |location=Washington DC |page=456}} The 1914 optic remains in situ in the tower; it weighs 4.5 tonnes and floats on 1.5 tonnes of mercury.

A separate lamp was used for the fixed red/white sector light, which continued to shine from its window lower down in the tower.{{Cn|date=July 2022}}

Having removed the two Holmes magneto-electric machines from the engine room, the Corporation of Trinity House presented one to the Institution of Electrical Engineers in 1915;{{cite book |last1=Parsons |first1=R.

The fog signal was improved in 1919 when a more powerful siren was installed, sounded through a pair of Rayleigh trumpets.[https://wondersofworldengineering.com/sentinels.html photo] (These replaced the twin Holmes trumpets formerly employed; the foghorn house was remodelled at the seaward corners to accommodate them). The siren gave a 4-second blast every minute.{{cite journal |title=Sentinels of the Sea |journal=Wonders of World Engineering |date=23 March 1937 |issue=4 |url=https://wondersofworldengineering.com/sentinels.html |access-date=2 November 2022}} Hornsby oil engines were installed to drive the compressors for the new siren.

In 1952 the lighthouse was again converted to run on electric power (this time using incandescent lamps, powered by mains electricity).{{cite book|last1=Jones|first1=Robin|title=Lighthouses of the North East Coast|date=2014|publisher=Halsgrove|location=Wellington, Somerset|pages=70–73}} The 4,500W bulbs used for the main light were the largest in the Trinity House service.{{cite book |last1=Jackson |first1=Derrick |title=Lighthouses of England and Wales |date=1975 |publisher=David & Charles |location=Newton Abbott |pages=110–111}} Should the electricity supply fail, a diesel generator would be engaged (and in the event that it too were to fail, an additional emergency battery lamp would be engaged). The mechanism which turned the lenses continued to be driven by clockwork at this time, until 1983 when it was replaced by a pair of electric motors.{{cite web|title=Local history society|url=http://www.ndfhs.org/Reports/st_2002_06.html}}

The fog signal was upgraded in 1953: a Stone Chance diaphone signal was installed and a pair of exponential horns replaced the Rayleigh Trumpets on top of the foghorn building. At the same time the engine room was provided with two new Reavell compressor sets, one driven by an electric motor, the other by a diesel engine. The diaphone produced a five-second blast every 30 seconds in poor weather, and remained in use up until 1988, when the lighthouse was decommissioned.

Souter Lighthouse was decommissioned by Trinity House in 1988,{{Cite web|url=http://www.chroniclelive.co.uk/news/local-news/ten-interesting-facts-south-shields-1342148|title = Ten interesting facts about South Shields|date = January 2012}} but continued to serve as a radio navigation beacon up until 1999 when it was finally closed.

As Souter was never automated, it remains much in its original operational state except for updates during its lifespan to its lantern and electrical apparatus.

Today the decommissioned Souter lighthouse is owned by the National Trust and open to the public; the engine room, light tower and keeper's living quarters are all on view. There is also an outdoor play area, Trusty Club and indoor activities to accommodate young visitors. Two of the former lighthouse keepers' cottages are used as National Trust holiday cottages. The lamps, lenses and foghorn remain in working order and are still activated from time to time 'on special occasions'.{{cite web |title=The lamp at Souter Lighthouse, a design marvel |url=https://www.nationaltrust.org.uk/features/the-lamp-at-souter-lighthouse-a-design-marvel |website=National Trust |access-date=3 November 2022}}
