Question: What fort other than Fort James, was built in Accra, Ghana?

full_context: Document 1: Castle Islands Fortifications, Bermuda: Several of the islands strung across the South entrance of Castle Harbour, Bermuda were fortified in the early days of the territory, hence the harbour's name. When official settlement of the archipelago by England began in 1612 (unofficial settlement having begun with the 1609 wrecking of the Sea Venture) the first permanent town, St. George's (then called "New London") was placed on the North side of St. George's Harbour. St. George's Harbour could be accessed directly by channels from the East. Those channels, however, were shallow, suitable, originally, only for small ships. As a consequence, and despite any major settlement on its shores, Castle Harbour was an important anchorage in the early years of the colony, with its main entrance, Castle Roads being an important route in from the open Atlantic for shipping. It was also a weakpoint, as it was remote from the defences of St. George's Harbour, and difficult to reach. It was quickly fortified and garrisoned by a standing militia.
Document 2: Fort Sekondi: Fort Sekondi, also Fort George, was an English fort on the Gold Coast (now Ghana), built in 1682 at Sekondi (earlier Zakonde and Secondee), next to the Dutch Fort Orange, which had been built in 1642. This first building was small, according to William Claridge: "[...] at Sekondi [...] Captain Henry Nurse, Agent for the English Company, also built a fort there a few years later. Both these buildings were of about the same size and only a gun-shot apart", and, "The Dutch Fort Orange was a very small place, being merely a square white house in a yard, mounting eight or ten guns on a terrace on the roof. The first English fort had been a very similar building [...]". This fort was destroyed on 1 June 1698, during the Dutch-Komenda war, and reduced to blackened outer walls. Although denied by the Dutch, reports and letters sent at the time indicated that the Dutch instigated the attack and that some plundered goods were taken to Castle Orange next-door. Attempts were made to rebuild it in 1700, though these had to be abandoned because of hostility from the indigenous population.
Document 3: Fort Orange (New Netherland): Fort Orange (Dutch: "Fort Oranje" ) was the first permanent Dutch settlement in New Netherland; the present-day city of Albany, New York developed at this site. It was built in 1624 as a replacement for Fort Nassau, which had been built on nearby Castle Island and served as a trading post until 1617 or 1618, when it was abandoned due to frequent flooding. Both forts were named in honor of the Dutch House of Orange-Nassau. Due to a dispute between the Director-General of New Netherland and the patroonship of Rensselaerswyck regarding jurisdiction over the fort and the surrounding community, the fort and community became an independent municipality, paving the way for the future city of Albany. After conquest of the region by the English, they soon abandoned Fort Orange (renamed Fort Albany) in favor of a new fort: Fort Frederick, constructed in 1676.
Document 4: Fort Amsterdam: Fort Amsterdam (subsequently named Fort James, Fort Willem Hendrick, Fort James (again), Fort William Henry, Fort Anne and Fort George) was a fort on the southern tip of Manhattan that was the administrative headquarters for the Dutch and then English/British rule of New York from 1625 or 1626 until being torn down in 1790 after the American Revolution.
Document 5: Fort Dansborg: Fort Dansborg, locally called Danish Fort, is a Danish fort located in the shores of Bay of Bengal in Tharangambadi in the South Indian state of Tamil Nadu. Fort Dansborg was built in the land ceded by Thanjavur king Ragunatha Nayak in an agreement with Danish Admiral Ove Gjedde in 1620 and acted as the base for Danish settlement in the region during the early 17th century. The fort is the second largest Danish fort after Kronborg. The fort was sold to the British in 1845 and along with Tharangambadi, the fort lost its significance as the town was not an active trading post for the British. After India's independence in 1947, the fort was used as an inspection bungalow by the state government till 1978 when the Department of Archaeology, Government of Tamil Nadu took over the control of the fort. The fort is now used as a museum where the major artifacts of the fort and the Danish empire are displayed.
Document 6: Fort James, Antigua and Barbuda: Fort James is a fort at the entrance to the harbour of St. John's, Antigua and Barbuda. The fort was built to guard St. John's harbour and is one of the many forts built by the British in the 18th century. Fear of a French invasion prompted the construction. It is located on a headland overlooking the town northwesterly. A powder magazine, several cannons and the foundation of the fort's wall remain. The main attraction today is the excellent view of the surrounding harbor.
Document 7: Jamestown, Virginia: The Jamestown settlement in the Colony of Virginia was the first permanent English settlement in the Americas. William Kelso writes that Jamestown "is where the British Empire began". It was established by the Virginia Company of London as "James Fort" on May 4, 1607 (O.S.; May 14, 1607 N.S.), and was considered permanent after brief abandonment in 1610. It followed several failed attempts, including the Lost Colony of Roanoke. Jamestown served as the capital of the colony of Virginia for 83 years, from 1616 until 1699.

Document 9: James Barnor: James Barnor (born 6 June 1929) is a pioneering Ghanaian photographer who has been based in London, UK, since the 1990s. His career spans six decades, and although for much of that period his work was not widely known it has latterly been discovered by new audiences. In his street and studio photography Barnor represents societies in transition: Ghana moving toward Independence, and London becoming a multicultural metropolis. He has said: "...I was lucky to be alive when things were happening...when Ghana was going to be independent and Ghana became independent, and when I came to England the Beatles were around. Things were happening in the 60s, so I call myself Lucky Jim." He was Ghana's first full-time newspaper photographer in the 1950s, and he is credited with introducing colour processing to Ghana in the '70s. It has been said: "James Barnor is to Ghana and photojournalism what Ousmane Sembène was to Senegal and African cinema."
