What is the Eddystone Lighthouse?

 title: 'Technical diagram of a mechanical component.'

The Eddystone rocks, lying about 14 miles off the harbour of Plymouth, are fully exposed to the south-western seas[1]. In 1696, Mr. Henry Winstanley undertook to erect a tower on the Eddystone[1]. On the 26th of November 1703, during the greatest British storm of which we have any record, the structure disappeared[1].

In 1706, a lease of 99 years was given by the Trinity House of London to a Captain Lovet, who was to erect another tower on this rock[1]. In August 1756, Smeaton commenced building a stone tower, adopting dovetailed joints for the stones[1].
