Ocracoke Inlet was a popular shipping lane during colonial times. Established in 1753, the town of Portsmouth functioned as a lightering port, where cargo from ocean-going vessels could be transferred to shallow-draft vessels capable of traversing Pamlico and Core Sounds. Portsmouth grew to a peak population of 685 in 1860. Though small, Portsmouth was one of the most important points-of-entry along the Atlantic coast in post-Revolutionary America. In 1846, two strong hurricanes cut Oregon Inlet and deepened the existing Hatteras Inlet to the northeast, making Ocracoke Inlet a less desirable shipping lane by comparison. The waters around Portsmouth's harbor also began to shoal up, hastening its decline as a port. The Civil War was yet another blow as many people fled to the mainland when Union soldiers came to occupy the Outer Banks. Many didn't return after the war had ended and the Village of Portsmouth continued its decline, sped along by the occasional hurricane. The mammoth 1933 Atlantic hurricane season also served as a benchmark in the island's population decline, though more as a focal point of memory and a symbol of decline than the real cause of it. A further blow was the decommissioning of the US Life-Saving Station there in 1937, and closing of the post office in 1959. In 1967 Portsmouth Island and village had already been acquired by the National Park Service then incorporated into the new Cape Lookout National Seashore. Last two elderly residents, Marian Gray Babb and Nora Dixon, left the island in 1971 after the death of Henry Pigott, who although approximately the same age was essentially their caretaker. In 1978 Portsmouth Village was added to the National Register of Historic Places.
Life in Portsmouth
The inhabitants of Portsmouth Village were heavily engaged in fishing and other maritime trades, like piloting and manning vessels, even building a small man-made island, Shell Castle, out of oyster shells for use as a shipping depot. Later many worked as fisherman and clammers. Much of Portsmouth's population was African American descending from the slaves brought to the island. After the Civil War most African Americans left Portsmouth but some families remained including Pigott family whose descendants were some of the island's last inhabitants: Henry and Lizzie Pigott. Under segregation, black and white children could not legally attend the one-room schoolhouse on Portsmouth Island together. The state never built a separate school for blacks, so African Americans who remained on the island in its declining years never received the benefits of a formal education. Inhabitants of the island lived without electricity, running water or refrigeration.
Portsmouth today
Now, 21 total buildings stand, including about a dozen dwellings and a few out-buildings. These are maintained as part of the Portsmouth Village Historic District. Of these the Salter House/visitor center, the one-room school, the Methodist Church, the Life-Saving Station, Henry Pigott's house and the Post Office/general store are open to the public during the summer. Now, especially during the summers, people often visit the island and camp out overnight on the beach. Facilities are very limited with a compost toilet near the Life-Saving Station and a restroom in the Salter house/visitors center, with no potable water, food, or electricity available.
Homecoming
Portsmouth is the location of an increasingly well-known "homecoming," currently celebrated every two years. The island homecoming has its origins in the early trips made back to the island by families who left prior to the 1960s and was originally affiliated with the Methodist and Primitive Baptist churches, primarily out of Cedar Island, North Carolina, where many inhabitants of Portsmouth had resettled. The homecoming began as a church- and family-based event but has become increasingly a secular celebration of Portsmouth's heritage, under the aegis of the National Park Service. Many people who have no direct family connection to the island participate in the homecoming.
Access
Portsmouth is reached by a passenger ferry from Ocracoke village. It is also accessible by four wheel drive vehicles, which cross Core Sound by ferry from Atlantic and use the beach and tracks on North Core Banks.
Portsmouth Island
Portsmouth Island lies to the east of North Core Banks, to which it is connected at most states of the tide. The limits of the island are not precisely determined and have varied over time. Older maps use the term for the island between Ocracoke Inlet and Whalebone Inlet
