Charity Butler Agyemang, a Ghananian tour guide looks on at the Cape Coast Slave Castle in Ghana, July 28, 2019. Charity said: "I think the 'Year of Return' has really helped in the tourism industry because we have a lot of people coming from the diaspora and beyond to invest and tour." Cape Coast Castle was used as a slaving post from where slaves were bought and sold and then shipped to the U.S. and other countries. The 400-year anniversary of the first slave boat to arrive in America from Africa has caused a rush of interest in heritage tourism in West Africa, as ancestors go back to ancient sites to delve into a dark and often hidden past.
