Fort William is situated on a hill in the little town of Cape Coast in Ghana.
In 1819-20 a small fort, called Smith's Tower, was built out of mud and stone on Dawson's Hill under Governor Hope-Smith. It was one of a chain of 3 lookout posts built on the hills in the town of Cape Coast around Cape Coast Castle, which were used for protecting the castle against Ashanti attacks and signalling purposes.
The present larger Fort William was built over the older fort in more durable materials. From the 1830's till the 1970's it was used as a lighthouse.
At present it houses several families of people who work at Cape Coast Castle. It can be visited free of charge but remind yourself that you are walking around someones home and a friendly tip is always appreciated.
Another surviving lookout post; Fort Victoria, is within viewing distance.
