Nantucket Harbor Range Lights

This article is about the current range lights in Nantucket Harbor. For the predecessor range lights, see Nantucket Beacon and Brant Point Light.

The Nantucket Harbor Range Lights are range lights that were built in 1908 to guide vessels through the narrow channel to Nantucket Harbor. They replaced an older arrangement involving the Nantucket Beacon and the Brant Point Light, which became unusable when the latter was replaced with a new tower.
