The first and second were destroyed. The third, also known as
Smeaton's Tower , is the best known because of its influence on lighthouse design and its importance in the development ofconcrete for building . Its upper portions have been re-erected in Plymouth as a monument.cite web | title = Eddystone Lighthouse | url = http://www.trinityhouse.co.uk/interactive/gallery/eddystone.html | publisher =Trinity House | accessmonthday = September 6 | accessyear = 2006]Winstanley's lighthouse
The first lighthouse on Eddystone Rocks was an octagonal wooden structure built by
Henry Winstanley . Construction started in 1696 and the light was lit on14 November 1698 . During construction, a Frenchprivateer took Winstanley prisoner, causing Louis XIV to order his release with the words "France is at war with England, not with humanity".cite web | title = Eddystone Lighthouse | url = http://www.trinityhouse.co.uk/interactive/gallery/eddystone.html | publisher =Trinity House | accessmonthday = September 6 | accessyear = 2006]The lighthouse survived its first winter but was in need of repair. The top was replaced, which causes some sources to state there have been five lighthouses on Eddystone Rock. Winstanley's tower lasted until the
Great Storm of 1703 erased almost all trace on27 November . Winstanley was on the lighthouse, completing additions to the structure. No trace was found of him.cite web | title = Eddystone Lighthouse History | url = http://www.eddystoneeel.com/LIGHTHOUSE%20HISTORY.htm | publisher = Eddystone Tatler Ltd | accessmonthday = September 7 | accessyear = 2006] cite web | title = The Great Storm of 1703 | url = http://www.bbc.co.uk/weather/features/understanding/1703_storm.shtml | publisher =BBC | accessmonthday = September 7 | accessyear = 2006]The cost of construction and five years' maintenance totalled £7,814 7s.6d, during which time dues totalling £4,721 19s.3d had been collected at 1d per ton from passing vessels.
Rudyard's lighthouse
[
Act of Parliament was allowed to charge passing ships a of 1d per ton. He commissionedJohn Rudyard (or Rudyerd) to design the new lighthouse, built as a conical wooden structure around a core of brick and concrete and first lit in 1709. This proved more durable, surviving nearly 50 years.cite web | title = Eddystone Lighthouse | url = http://www.trinityhouse.co.uk/interactive/gallery/eddystone.html | publisher =Trinity House | accessmonthday = September 6 | accessyear = 2006]On the night of
December 2 1755 , the top of the lantern caught fire, probably through a spark from one of the candles used to illuminate the light. The three keepers threw water upwards from a bucket but were driven on to the rock as the tower burnt down. They were rescued by boat. Henry Hall, who was 84 or 94 at the time, died fromlead poisoning because of the moltenlead from the lantern roof he had ingested fighting the fire.cite web | title = Eddystone Lighthouse | url = http://www.trinityhouse.co.uk/interactive/gallery/eddystone.html | publisher =Trinity House | accessmonthday = September 6 | accessyear = 2006] A report on this case oflead poisoning was submitted to theRoyal Society by the physician Dr Edmund Spry, and the piece of lead is now in the collections of theNational Museums of Scotland .cite book |last=Palmer |first=Mike |title=Eddystone: the Finger of Light |edition=2nd edition |date=2005 |publisher=Seafarer Books |location=Woodbridge, Suffolk |isbn=095470620X ]meaton's lighthouse
The third lighthouse marked a major step forward in the design of such structures.
Recommended by the
Royal Society ,civil engineer John Smeaton modelled the shape on anoak tree , built ofgranite blocks. He pioneered 'hydraulic lime ', aconcrete that will set under water, and developed a technique of securing the granite blocks usingdovetail joint s andmarble dowel s.

It remained in use until 1877 when it was discovered that the rocks upon which it stood were eroded—each time a large wave hit the lighthouse it would shake from side to side. Smeaton's lighthouse was rebuilt on
Plymouth Hoe , inPlymouth , as a memorial.The foundations and stub of the tower remain, close to the new and more solid foundations of the current lighthousecite web | title = Eddystone Lighthouse | url = http://www.trinityhouse.co.uk/interactive/gallery/eddystone.html | publisher =

The current, fourth, lighthouse was designed by James Douglass, using Robert Stevenson's developments of Smeaton's techniques. The light was lit in 1882 and is still in use. It is operated by
Trinity House . It was automated in 1982, the first Trinity House lighthouse to be converted. The tower has been changed by construction of ahelipad above the lantern, to allow maintenance crews access.cite web | title = Eddystone Lighthouse | url = http://www.trinityhouse.co.uk/interactive/gallery/eddystone.html | publisher = Trinity House | accessmonthday = September 6 | accessyear = 2006]The tower is 49 metres(161 ft) high, and its white light flashes twice every 10 seconds. The light is visible to 22
nautical miles (41 kilometres), and is supplemented by afog signal of 3 blasts every 60 seconds.cite web | title = Eddystone Lighthouse | url = http://www.trinityhouse.co.uk/interactive/gallery/eddystone.html | publisher = Trinity House | accessmonthday = September 6 | accessyear = 2006]References in the media
