Description: An informational sign near the lighthouse reads:

"In 1771, Royal Governor John Wentworth had a lighthouse built here on Fort Point. Constructed of wood and hexagonal in shape, the Portsmouth Light was the tenth to be built in North America. One of the duties of the lighthouse keeper was to keep the wicks of the oil lanterns trimmed so the light wouldn't die out.

Celia Thaxter, the Isles of Shoals' foremost poet, remembers helping her father, the keeper of the White Island Light in the mid-1800s:

I lit the lamps in the lighthouse tower
For the sun dropped down and the day was dead.
They shone like a glorious clustered flower, -
Ten golden and five red.

Fort Point and the light were granted to the federal government in 1791. The iron tower, present today, was built to replace the wooden structure in 1877.

Today, the Portsmouth Light still flashes. A computer-controlled electrified lens which emits a green light has replaced the lanterns of two hundred years ago."

The Friends of Portsmouth Harbor Lighthouse, a chapter of the American Lighthouse Foundation that is responsible for maintenance of the lighthouse, occasionally offers open houses at the lighthouse.
