Ida Lewis worked at which Light House?

Ida Lewis is famously known for her long tenure as the lighthouse keeper of Lime Rock Lighthouse in Newport, Rhode Island, which she began in the mid-19th century. She is celebrated for her heroic rescues and for her dedication to maintaining the lighthouse, often referred to as one of the first female lighthouse keepers in the United States. Her extraordinary service and contributions to maritime safety have made Lime Rock Lighthouse synonymous with her legacy.

The other locations mentioned, such as the Statue of Liberty, Point Reyes, and Cape Cod, are significant in their own right, but none are directly associated with Ida Lewis's remarkable history and achievements in lighthouse navigation and safety. Thus, Lime Rock stands out as the correct answer.
