The proposed site offered several advantages. The ground consisted of hard sand, elevated higher than Ship Island, and nearby sources provided abundant lumber and high-quality brick. A brick structure was initially recommended as economical and durable, with an estimated appropriation of $20,000. However, further study revealed that the island’s instability made a heavy masonry tower impractical.
By 1872, the Lighthouse Board refined its recommendation, emphasizing the necessity of a light at the eastern end of Horn Island to complete the chain of aids to navigation in Mississippi Sound and to mark Horn Island Pass from the Gulf. A screw-pile lighthouse of the type then commonly used in shallow coastal waters was proposed, with an estimated cost of $22,000. Congress authorized this appropriation on March 3, 1873.
That same year, a detailed survey of Horn Island Pass and the eastern end of the island was conducted. The results confirmed that a fourth-order wooden lighthouse supported on iron screw-piles—similar to the Cat Island Lighthouse—was the most suitable design. Contracts for the iron foundation and lantern were awarded to a Baltimore firm, while the wooden superstructure was constructed by hired labor.
The ironwork was completed and delivered in October 1873 but temporarily stored at Fort Morgan, Alabama, until the wooden framing was ready. In January 1874, the entire structure was transported to Horn Island aboard the lighthouse tender Pharos. Installation proved difficult. All of the original foundation screws broke during installation, causing months of delay while replacements were cast. Once new screws were obtained, work resumed in March, and five iron screw-piles were finally set successfully.
Construction advanced rapidly thereafter. By early June 1874, the lighthouse was complete, and on the evening of June 30, 1874, the light was exhibited for the first time. The structure consisted of a square wooden dwelling mounted on five iron screw-piles and surmounted by a lantern with an iron parapet. Its fourth-order lens displayed a fixed white light varied by red flashes, making it distinguishable from neighboring beacons. This was the first new lighthouse established on the Gulf Coast after the Civil War.
In 1875, a fog bell operated by machinery—authorized by Congress the previous year—was added to the station, enhancing its usefulness during frequent periods of reduced visibility.

With erosion accelerating, the Board ordered the lighthouse moved across the island to its north side. In 1881, the structure was relocated approximately one hundred yards north and placed on thirteen creosoted wooden piles driven sixty feet into the sand. The building was thoroughly repaired and repainted. Yet the island itself continued to migrate. By 1882, sand had built up north of the station, placing it once again in the Gulf rather than Mississippi Sound. Despite these changes, the deeply embedded piles ensured the structure’s stability.
Further reinforcement followed in 1882 and 1883, including iron tension rods to stiffen the foundation. The original iron screw-piles were removed and stored, and mineral-oil lamps replaced earlier illumination systems. By 1885, however, the station stood in seven feet of water, and heavy gales caused such severe vibration that the lens mechanism often failed to operate properly. It was clear that another relocation would soon be necessary.
In 1887, a completely new structure was built approximately a mile west and south of the original site, on what was believed to be the most stable portion of Horn Island. The new station, completed on May 15, 1887, consisted of a one-and-a-half-story framed dwelling topped by a lantern, with multiple living spaces and separate outbuildings, including an oil house, wood shed, and large cistern. The lens and lighting apparatus were transferred from the old lighthouse. The former structure was dismantled and stripped of reusable materials, leaving its piles and frame as a daymark. The fog signal was discontinued that same year.
Over the next two decades, Horn Island Light Station underwent continual maintenance and incremental improvements. Surveys were conducted, reservation boundaries marked, fences erected to protect vegetation from grazing cattle, and new oil houses, cisterns, wharves, and plank walks constructed. Despite these efforts, erosion remained relentless.
By 1900, surveys revealed that the sand hill supporting the lighthouse was washing away rapidly, placing the station once again in danger. Orders were issued to move the structure into shallow water north of its existing location, where it could be supported on wooden piles encased in terra-cotta pipe filled with cement mortar. This relocation was completed in 1901, with the station reestablished on seventeen protected foundation piles in approximately two feet of water. Additional improvements followed, including new braces, rebuilt storehouses, and expanded wharf and boat facilities.
All previous efforts were rendered futile by the catastrophic hurricane of September 27, 1906. The storm obliterated the eastern end of Horn Island entirely. The lighthouse was destroyed, and Keeper Charles Johnson, along with his wife and daughter, perished in the storm; their bodies were never recovered. Where the lighthouse once stood, a navigable channel now cut through the island. Horn Island, long known for its instability, appeared to have finally defeated permanent occupation.

This final Horn Island Light proved far more durable. Though it endured hurricanes—including severe storms in 1917—it remained intact, thanks to its offshore foundation. During this period, keepers and assistant keepers distinguished themselves through acts of bravery, rescuing shipwrecked crews and disabled mariners, often under dangerous conditions.
In 1941, the Coast Guard automated the light and removed the keepers, although personnel were temporarily reassigned during World War II. Full automation followed in 1951. By the early 1960s, improved navigational technology and the construction of range lights between Horn Island and Petit Bois Island rendered the lighthouse redundant. In 1961, Horn Island Lighthouse was officially discontinued.
