Smeaton's Tower is a memorial to civil engineer
John Smeaton
John Smeaton (8 June 1724 – 28 October 1792) was a British civil engineer responsible for the design of bridges, canals, harbours and lighthouses. He was also a capable mechanical engineer and an eminent physicist. Smeaton was the fir ...

History
Background
England’s coasts are notorious for rough weather, dangerous seas and deathly obstacles. The Eddystone rocks are among them.
There were several attempts were made to place a marker on these reefs. The first attempt was called the Winstanley Lighthouse.
After it was destroyed in the 1703 storm, a second one called the Rudyard lighthouse was built.
This one was also destroyed, this time by a fire in 1755.

Construction
![Smeaton dovetailing](https://upload.wikimedia.org/wikipedia/commons/f/f5/Smeaton_dovetailing.jpg)
Smeaton had to build his lighthouse to be strong enough to survive the elements (the first lighthouse was destroyed in a storm).
He began by designing his lighthouse to resemble an oak tree. This in itself made the tower into a strong shape.
He rediscovered the use of

, where Smeaton built a jetty and a workyard in the south-western corner of the harbour to unload and work on stones. Timber rails of gauge were laid for four-wheeled flat trucks, which were used to move masonry around the site. A 10-ton ship named ''Eddystone Boat'' was based here, and transported worked stones out to the reef. The ship carried the 2¼-ton foundation stone out in the morning of 12 June 1756.

The work was completed in August 1759 at a cost of £40,000 (£ with inflation).

Each candle weighed between . A timepiece placed alongside the light was set to chime every half-hour (30 min), alerting the lighthouse keeper to the need to replace expired candles.
The lighthouse candles were replaced by oil lamps and reflectors from 1810.
