The Eddystone Lighthouse is on the dangerous Eddystone Rocks, 9 miles south of Rame Head, Cornwall. The rocks, a sharp reef composed of Precambrian gneiss, stand in the shipping route towards Plymouth Sound, presenting a serious danger, and for this reason a lighthouse was first built here in 1699.
The current structure is the fourth to be built on the site. The first and second were destroyed by storm and fire. 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 of concrete for building. Its upper portions have been re-erected in Plymouth as a monument.[1] The first lighthouse, completed in 1699, was the world's first open ocean lighthouse although the Cordouan lighthouse preceded it as the first offshore lighthouse.[2]
The need for a light
The Eddystone Rocks are an extensive reef approximately 12 miles SSW of Plymouth Sound, one of the most important naval harbours of Britain, and midway between Lizard Point and Start Point. They are submerged at high spring tides and were so feared by mariners entering the English Channel that they often hugged the coast of France to avoid the danger, which thus resulted not only in shipwrecks locally, but on the rocks of the north coast of France and the Channel Islands.[3] Given the difficulty of gaining a foothold on the rocks particularly in the predominant swell it was a long time before anyone attempted to place any warning on them.
Winstanley's lighthouse
The first lighthouse on Eddystone Rocks was an octagonal wooden structure built by Henry Winstanley. The lighthouse was also the first recorded instance of an offshore lighthouse.[2] Construction started in 1696 and the light was lit on 14 November 1698. During construction, a French privateer took Winstanley prisoner and destroyed the work done so far on the foundations, causing Louis XIV to order Winstanley's release with the words "France is at war with England, not with humanity".[1]
The lighthouse survived its first winter but was in need of repair, and was subsequently changed to a dodecagonal (12 sided) stone clad exterior on a timber framed construction with an octagonal top section as can be seen in the later drawings or paintings, one of which is reproduced here. This gives rise to the claims that there have been five lighthouses on Eddystone Rock. Winstanley's tower lasted until the Great Storm of 1703 erased almost all trace on 27 November. Winstanley was on the lighthouse, completing additions to the structure. No trace was found of him, or of the other five men in the lighthouse.[4]
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 one penny per ton from passing vessels.
Rudyard's lighthouse
Following the destruction of the first lighthouse, Captain John Lovett[5] acquired the lease of the rock, and by Act of Parliament was allowed to charge passing ships a toll of one penny per ton. He commissioned John Rudyard (or Rudyerd) to design the new lighthouse, built as a conical wooden structure around a core of brick and concrete. A temporary light was first shone from it in 1708[6] and the work was completed in 1709. This proved more durable, surviving nearly fifty years.[1]
On the night of 2 December 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 onto the rock and were rescued by boat as the tower burnt down. Keeper Henry Hall, who was 94 at the time, died from ingesting molten lead from the lantern roof.[1] A report on this case was submitted to the Royal Society[7] by the physician Dr. Edward Spry, and the piece of lead is now in the collections of the National Museums of Scotland.[8]
Smeaton'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 an oak tree, built of granite blocks. He pioneered 'hydraulic lime', a concrete that cured under water, and developed a technique of securing the granite blocks using dovetail joints and marble dowels. Construction started in 1756 at Millbay[9] and the light was first lit on 16 October 1759.[1]
Smeaton's lighthouse was 59 feet high and had a diameter at the base of 26 feet and at the top of 17 feet.
In 1841 major renovations were made,[10] under the direction of engineer Henry Norris of Messrs. Walker & Burges, including complete repointing, replacement water tanks and filling of a large cavity in the rock close to the foundations. It remained in use until 1877 when erosion to the rocks under the lighthouse caused it to shake from side to side whenever large waves hit.[11]
Smeaton's lighthouse was rebuilt on Plymouth Hoe, in Plymouth, as a memorial, known as Smeaton's Tower. William Tregarthen Douglass supervised the dismantling and removal of Smeaton's Tower. The re-erected tower on the Hoe is now a tourist attraction.
The foundations and stub of the tower remain, close to the new and more solid foundations of the current lighthouse[1] – the foundations proved too strong to be dismantled so the Victorians left them where they stood.
An 1850 replica of Smeaton's lighthouse, Hoad Monument, stands above the town of Ulverston in Lancashire as a memorial to naval administrator Sir John Barrow.
Douglass's lighthouse
The current, fourth, lighthouse was designed by James Douglass, using Robert Stevenson's developments of Smeaton's techniques. By April 1879 the new site, on the South Rock. was being prepared during the 3½ hours between ebb and flood tide. The supply ship Hercules was based at Oreston, now a suburb of Plymouth, and the stone was prepared at the Oreston yard and supplied from the works of Messrs Shearer, Smith and Co of Wadebridge.[12][13]
The light was lit in 1882 and is still in use. It was automated in 1982, the first Trinity House 'Rock' (or offshore) lighthouse to be converted. The tower has been changed by construction of a helipad above the lantern, to allow maintenance crews access.[14]
The tower is 161 feet high, and its white light flashes twice every 10 seconds. The light is visible to 22 nautical miles, and is supplemented by a foghorn of 3 blasts every 62 seconds.[1]
In literature and popular culture
- The lighthouse inspired a sea shanty, frequently recorded, that begins "My father was the keeper of the Eddystone light / And he slept with a mermaid one fine night / From this union there came three / A porpoise and a porgy and the other was me!".[15] Another version has the fourth line as "Two of them were fishes and the other was me." There are several verses.
- The lighthouse has been used as a metaphor for stability.[16]
- In the Goon Show episode Ten Snowballs that shook the World (1958), Neddie Seagoon is sent to Eddystone Lighthouse to warn the inhabitants that Sterling has dropped from F-sharp to E-flat.
- The lighthouse is celebrated in the opening and closing movements of Ron Goodwin's Drake 400 Suite. The movement's main theme was directly inspired by the lighthouse's unique light characteristic.[17]
- A novel based on the building of Smeaton's lighthouse, containing many details of the construction, was published in 2005.[18]
- The lighthouse is referenced twice in Herman Melville's epic novel Moby-Dick; at the beginning of Chapter 14, "Nantucket": "How it stands there, away off shore, more lonely than the Eddystone lighthouse.", and in Chapter 133, "The Chase - First Day": "So, in a gale, the but half baffled Channel billows only recoil from the base of the Eddystone, triumphantly to overleap its summit with their scud."
- The lighthouse is referred to in "Daddy was a Ballplayer" by the Canadian band Stringband, and follows a similar line to the sea shanty.
- "The Most Famous of All Lighthouses," the third chapter of The Story of Lighthouses (Norton 1965) by Mary Ellen Chase, is devoted to the Eddystone Lighthouse.
