Fort Prinzenstein (Danish: Fort Prinsensten) is a fort located at Keta, Ghana which was used in the slave trade.[1] Many such forts were built in Africa, but Prinzenstein is one of the few that lie east of the Volta River.[1] It was initially built by Danish traders in 1784 for defensive purposes in a war against the Anlo Ewe and to keep the area safe from other colonial powers. [2] The fort was used as a dungeon for slaves awaiting transportation to the Caribbean. In 1850 the fort, along with the rest of the Danish Gold Coast was sold to Britain.[3] The fort was used as a prison for a period before it was partially destroyed by the sea in 1980. [4] The remains of the fort are now visited by tourists. [5]
