Solomons in Calvert County, Maryland — The American Northeast (Mid-Atlantic)
The Business End of a Screwpile
Screwpile lighthouses were first developed by Irish engineer Alexander Mitchell, who patented his invention in 1833. Screwpiles became widely used throughout the world as a foundation system for piers and bridge as well as lighthouses.
Surprisingly, little has come to light describing how the heavy plies were supported and driven at the precise angles required. In earlier years, a barge-mounted capstan, rotated by a team of men, drove the piles. It is known, however, that the seven piles that supported Drum Point Lighthouse were set in the remarkably short time of three days.
