Overview
Mona Island Light, also referred to as the Faro de Isla de la Mona, is a historic lighthouse situated on the western coast of Mona Island, a small island administered by Puerto Rico in the Caribbean Sea. The lighthouse was constructed to aid navigation for vessels traveling between the main island of Puerto Rico, the Dominican Republic, and other Caribbean ports.
Location
- Island: Mona Island (Isla de la Mona)
- Coordinates: Approximately 18°06′N 67°55′W (exact coordinates vary among sources)
- Position on island: Western shoreline, overlooking the Mona Passage
Historical Background
- Construction: The lighthouse was built in 1908 under the authority of the United States Lighthouse Board, which oversaw lighthouse construction in U.S. territories after the Spanish–American War.
- Commissioning: It entered service in 1909, providing a vital navigational aid for ships crossing the Mona Passage, a frequently used route for commercial and naval traffic.
- Optical Apparatus: The light originally employed a third‑order Fresnel lens, a common lighthouse technology of the period, delivering a characteristic flashing pattern visible for several nautical miles.
Architectural Features
- Structure: The lighthouse comprises a masonry (brick and stone) cylindrical tower, approximately 20 m (65 ft) tall, integrated with a lantern room at the summit.
- Materials: Construction utilized locally sourced stone and imported brick, consistent with early‑20th‑century lighthouse design in the Caribbean.
- Color Scheme: Historically painted white with a contrasting lantern dome; current paint condition varies due to exposure and limited maintenance.
Operational History
- Service Period: The light remained operational for the majority of the 20th century, guiding maritime traffic through the Mona Passage.
- Automation: The lighthouse was automated in the mid‑20th century, reducing the need for resident keepers.
- Deactivation: Official records indicate the lighthouse was deactivated in the 1970s; the exact year is cited as 1975 by several maritime archives, though some sources list a slightly earlier date.
Current Status
- Preservation: The structure is presently in a state of partial ruin, with the tower and lantern surviving but suffering from environmental degradation, including corrosion from salt air and damage from hurricanes.
- Ownership: The site remains under the jurisdiction of the Puerto Rico Department of Natural and Environmental Resources, which manages Mona Island as a nature reserve.
- Access: Public access to Mona Island is highly restricted to protect its fragile ecosystem; consequently, visits to the lighthouse are limited to authorized scientific, conservation, or government personnel.
- Cultural Significance: Mona Island Light is recognized as a historic maritime landmark, representing early U.S. lighthouse construction in the Caribbean and the strategic importance of the Mona Passage for navigation.
