Mona Island Light - Puerto Rico

The main purpose of the light was to guide ships through the Mona Passage. The surface up the side of the island was so rough that the workmen had to blast a trail to the top. Through presistence and hard work the workmen transported the parts to the top, and soon began erecting a skeleton tower whose second-order lens was fifty-two feet above the ground. The keeper exhibited the light April 30, 1900.
