The Fort Wetherill Mine Observation Station is a fascinating abandoned structure in Jamestown, Rhode Island. There is not a lot of documented history behind this location, but some information can be extracted from historical records. Fort Wetherill was established during the Endicott Period in 1895. It remained active until 1945 and many changes occurred over the years. During World War 2, the fort started using mines to protect Newport Harbor and Narragansett Bay. There were over 300 mines planted on the east and west sides of Conanicut Island during WW2. To support the mines, a storehouse, wharf, and tramway were built. Also, this observation station was constructed.

This abandoned old building was a Mine Observation Station. It was situated at the top of a hill and offered lookouts sweeping views of the ocean, bay, and harbor. If any enemies were spotted, the lookouts could inform nearby guns and also control the mines deployed.

After World War 2 ended, the Fort Wetherill Mine Observation Station was decommissioned and abandoned. It has sat high on this hill for decades now. The structure itself is slowly degrading and being reclaimed by nature. It is a must-visit spot when in Fort Wetherill State Park!
