In 2020 the High Museum of Art in Atlanta, Georgia exhibited new work by Joe of Gold Coast fortresses. The exhibit featured seven buildings that served as the way stations for Africans who were sold into slavery, put on ships, and sent to the Americas and the Caribbean in the sixteenth through nineteenth centuries. The works are large, painted wood architectural sculptures and include the Cape Coast Castle, Fort Orange, Christiansborg Castle, Fort Patience, and Fort St. Sebastian. The process of making the works included visits to the sites, taking pictures, and drawing sketches.
