Hope Town is the home to the famous Elbow Reef Lighthouse. Probably the most recognizable landmark in Abaco, the lighthouse is one of the last manual lighthouses in the world. The lamp burns pressurized Kerosene oil with a wick and mantle. The Fresnel lenses concentrate the mantle’s light into a beam directed straight towards the horizon. The lenses and burner equipment, weighing 8,000lbs, float in a circular lubricated tub. This reduces friction so that the 700lbs of weight, when wound up to the top of the tower by hand, smoothly rotates the 4-ton apparatus once every 15 seconds. The lighthouse keeper on duty must wind up the weights every 2 hours in order for the red and white candy-striped lighthouse to be seen from 17 miles away.
