The Eddystone Lighthouse Story
The Reef That Killed Them
Fourteen miles south of Plymouth Sound, a low cluster of gneiss and schist outcrops barely breaks the surface of the English Channel. The rocks are elongated east to west for about half a mile, always awash in any kind of sea, and invisible in bad visibility until a vessel is already among them. The name — Eddystone — probably derives from the tidal eddies the reef generates. The coast of Devon lies to the north; the open Atlantic begins to the south. Ships on the western approaches, inbound for Plymouth or the Bristol Channel, have always had to either pass to seaward of the reef or find a clear inshore passage. On a dark night, or in fog, or in the kind of driving westerly that is routine in the Channel approaches, the Eddystone was a death trap.
How many vessels were wrecked on it before anyone thought seriously about marking it is not precisely recorded. The political pressure to do something crystallised in the 1690s, and the first lighthouse on the Eddystone Rocks was completed in 1698 — making it, at that date, the world's first lighthouse built on a fully exposed, wave-washed reef with no land support whatsoever. What followed was a sequence of disasters, redesigns and eventual triumphs that makes the Eddystone the most dramatic single lighthouse narrative in the history of the profession.
Winstanley's Tower: 1698–1703
Henry Winstanley was an eccentric English engineer and self-publicist who had ships wrecked on the Eddystone and resolved to mark the reef himself. His first structure, completed in 1698, was a timber and iron construction that managed to be both under-engineered and extravagant in decoration — Winstanley added weathervanes, external galleries and ornamental flourishes to a foundation that was already inadequate for the sea conditions. The light itself was a candle lantern of debatable effectiveness.
The structure was modified and expanded in 1699, adding height and more accommodation. Winstanley was famously confident in his work, reportedly expressing a wish to be in the lighthouse during the greatest storm that had ever been known. In November 1703, England was struck by what remains the most severe storm recorded in its history. The Great Storm of 26–27 November killed an estimated 8,000 people across the country, destroyed or dismasted hundreds of ships in the Channel and the North Sea, and unroofed churches across southern England. When the storm cleared, the Eddystone lighthouse had vanished. Winstanley and the five other people in the tower with him — including workers who had been repairing damage from an earlier storm — were never found. Not a timber remained on the rock.
Rudyerd's Timber Tower: 1709–1755
The second Eddystone lighthouse was built by John Rudyerd, a London silk merchant with no engineering training but considerable practical sense. Learning from the complete failure of Winstanley's overbuilt, wind-catching structure, Rudyerd designed a slender timber tower sheathed in planking, with a circular section tapering from a broad base to a lantern room. The form was more hydrodynamic and the construction more disciplined. The first light was shown on 28 July 1709. The tower survived for 46 years — by far the longest-lived of the four Eddystone structures.
Its end was not the sea but fire. On 2 December 1755, the candles in the lantern room ignited the lantern woodwork, and the tower burned. The keeper Henry Hall, then 94 years old, looked up at the fire and swallowed a quantity of molten lead from the burning roof. He survived long enough to be treated by a doctor, who was disbelieved when he reported the ingestion; after Hall died twelve days later, a post-mortem revealed a solid piece of lead approximately 200 grams in weight in his stomach, and the story passed into medical literature. The timber tower was destroyed to the waterline.
Smeaton's Stone Tower: 1759–1877
John Smeaton's response to the failure of Rudyerd's tower was a complete rethinking of lighthouse structure. Smeaton was a professional civil engineer — arguably the first person to describe himself as such — and he approached the problem systematically. Timber burned and could be damaged by rot; the new tower would be masonry. The section would be modelled on the bole of an oak tree — broad-based, tapering upward, with a concave hyperbolic profile calculated to shed wave energy rather than resist it directly. Each course of masonry would be dovetailed and joggled to its neighbours, and secured with marble joggles, so that the tower would behave structurally as a single unit rather than a stack of independent rings.
Construction began in 1757 and the light was first shown on 16 October 1759. The tower was 22 metres tall and stood, essentially unchanged, for 118 years. Smeaton's design was immediately recognised as a fundamental advance in lighthouse engineering, and its principles were copied by Robert Stevenson for Bell Rock (1811) and by Alan Stevenson for Skerryvore (1844). When the tower was finally decommissioned in 1877, it was not because the structure had failed — it was because the rock beneath it had been undermined by wave scour and was beginning to show signs of instability. The tower itself remained sound.
Smeaton's tower was not demolished. It was dismantled, stone by numbered stone, and re-erected on Plymouth Hoe, where it stands today as a museum and the most prominent monument on the seafront. The base stump of the original, comprising the lowest courses that could not be removed without excessive cost, remains on the Eddystone rock beside the current lighthouse.
Douglas's Tower: 1882 to Present
The fourth Eddystone lighthouse was designed by James Douglas, engineer to Trinity House, and was first lit on 18 May 1882. Douglas learned from Smeaton and improved on him: the new tower is 49 metres tall, substantially larger than its predecessor, and is built entirely from Cornish granite — 2,171 blocks, each dovetailed and bolted, with the foundation courses solid-filled to eliminate the hollow base chambers that had concerned engineers about the earlier tower. The section is hyperbolic, like Smeaton's, but with a steeper flare at the base.
The light character is two white flashes every ten seconds, visible for 20 nautical miles. The tower was automated on 18 May 1982 — exactly a century after it was first lit — and is now monitored from Trinity House's control centre in Harwich. The helicopter landing platform, added in the second half of the twentieth century, caps the lantern room with a flat circle that gives the tower its distinctive modern profile when seen from the sea.
The Stump and the Rivalry
The stump of Smeaton's tower still stands beside Douglas's, visible from passing vessels as a low cylindrical mass of granite projecting from the rock at the base of the current tower. It is one of the most historically resonant pieces of masonry in British civil engineering — the remains of the structure that proved offshore rock lighthouses were buildable, and that provided the template for everything that followed.
The question of credit between Smeaton and his successors was occasionally contentious. Robert Stevenson, who was deeply conscious of his debt to Smeaton, was less ready to acknowledge the contributions of John Rennie to Bell Rock. Alan Stevenson gave Smeaton explicit acknowledgment in his account of Skerryvore. The tradition of attribution that runs from Winstanley's catastrophic improvisation through Rudyerd's reasonable but flammable timber to Smeaton's scientific masonry and Douglas's Victorian granite monolith is one of the clearest examples in engineering history of knowledge genuinely accumulating from one generation to the next.
Visiting the Eddystone
The current lighthouse is visible from Plymouth Hoe on clear days through binoculars, and boat trips past the reef run from Plymouth in summer. Smeaton's Tower on the Hoe is open to visitors as a museum and contains display material on all four Eddystone lighthouses, including models of each structure. For the full context of where the reef sits relative to the Devon coast and the western approaches, Open the map — the Eddystone's position 14 miles offshore, directly on the main inbound shipping track, makes its importance immediately apparent.
The story of the Eddystone is ultimately a story about what it takes to learn from failure. Winstanley died believing his tower was adequate. Rudyerd built adequately but could not foresee fire. Smeaton solved the structural problem with rigour and clarity of thought. Douglas refined the solution with more material and better craft. The current tower has been standing for over 140 years without structural modification. That continuity on one of the most exposed sites in the English Channel is the best evidence that the problem, eventually, was solved.
