Fort Vernon was a military structure designed to facilitate the Atlantic slave trade.

The Royal African Company built the fort in 1742 near Prampram, a town in the Greater Accra Region of Ghana.

It was built out of cheap materials – rough stones and swish.

The British rebuilt it in 1806, but it soon started to collapse and was abandoned in about 1816.

[1] Because of its importance during the slave trade and its testimony to European economic and colonial influence in West Africa, the fort was inscribed on the UNESCO World Heritage List in 1979, along with several other forts and castles in Ghana.
