Sombrero Key Lighthouse
In 1857 delivery of the lighthouse parts was made to Duck Key which served as the construction headquarters. Meade sank the eight outer iron piles through 8 foot diameter pads 10 feet into the coral for the foundation of the structure. A final pile was sunk in the center of the piles. Each pile could support up to 64 tons. Six additional levels of piles were built atop the foundation tapering from 56 feet at the bottom to 15 feet at the top of the structure.
