The building of the Eddyntone Lighthouse has made Smeaton's name a household word among successive generations of 

 Englishmen until to-day. It was built in 1756-9 of large shaped granite blocks, and was the greatest work of its kind 

 hitherto undertaken, and remained in use until 1879, when it was rebuilt as a monument on Plymouth Hoe, as the rock 

 which formed the foundation had become greatly weakened by the sea. 



' Smeaton's .story of the Eddystone lighthouse is t'^ld in a very effective manner. It possesses an interest almost 

 dramatic, exhibiting a contest between a strong, skilled, and determined man, and the most tremendous forces of nature.' 

 — Samuel Smiles.
