The fort was built by the British between 1765 and 1771, to ward off Dutch colonial ambitions.
The abolition of the slave trade in the Gold Coast diminished the importance of the fort, as a result it became too expensive, so the British abandoned it in 1819 after which, the Dutch took ownership over the fort in 1868. The fort was bombed in 1873, during a British attack on Beyin on account of its coalition with the Asante Kingdom.
Fort Apollonia was constructed in a different style to all the other forts on the Gold Coast, It had a stronger seaward bastion that served as a defense with in- cells for storing the bought slaves from the interior parts of the country. There is a total of four bastions all of different shape and size. The western bastion was the largest, it contained nine mounted guns for protection against attacks. The other three bastions were smaller and only carried up to five guns.
In the beginning of the 20th century the fort became a ruin but was restored in the 1960s by the Ghana Museums and Monuments Board. Apart from the fort, there is a beautiful sandy beach on which you can spend hours on end sunbathing, playing football, pretty much anything you want. It is also one of the few sites in Ghana where the spectacular European oyster catcher is regularly seen.
