Historical Information:
- Requests from seven shipping companies in 1891 convinced the government to establish a light station on Spring Point Ledge. The ledge is a dangerous obstacle on the west side of the entrance to Portland Harbor.
- A 54 foot caisson or “sparkplug” style light was built on the ledge. A fifth order Fresnel lens was installed in the tower. Electricity was run to the station in 1934. Responsibility for the Portland Breakwater Light was transferred to the keepers at Spring Point Ledge after both stations received electricity.
- A 900 foot breakwater was built in 1951 to connect the lighthouse with the mainland.
- In 1998 the light was transferred to the Spring Point Ledge Light Trust. The trust has started restoring the light. The group offers occasional “open house” tours to the public. The light is an active aid to navigation.
