Joesph Smeaton - built a lighthouse,1750

Some random information from my university course - thought it might be of interest to someone.

In 1750, Joesph Smeaton/Smeeton was commisioned to build a lighthouse at the southwesternmost point of cornwall. Previous to this, most lighthouses were made of wood, which obviously was a problem when they were lighted with kerosene lamps.

Joesph planned to build this lighthouse out of granite, but the cements and mortars of the day were very weak. He struck upon the idea of using impure limestone, which contained clays, rather than purifing it, and this turned out to be by far the strongest cement. It was not improved upon for almost a hundred years.
