The New Haven Harbor Light (aka the Five Mile Point Light) is a lighthouse located in the aptly named Lighthouse Point Park in New Haven, Connecticut. The lighthouse and the park are right next to the beach and mark the harbor entrance to Long Island Sound. While it is not the original light on the site, it is still pretty old, having been built in 1847 for $10,000. The light is only 65 feet tall and is no longer operational, as it was retired in 1877. It has served since then as an attraction in the New Haven park.
