David Adjaye has designed the Barbados Heritage District, including a monument to serve as a reminder of slavery. The location is Newton Plantation outside Bridgetown, capital of the small Caribbean island country which recently became a parliamentary republic in and of its own accord. The memorial will be next to the site of the burial of an estimated 570 African slaves. A dome pavilion built with red earth will rise beside a square formed by 570 timber columns. It is estimated that 400,000 West Africans were shipped to Barbados in the 17th and 18th centuries, when the island was a British colony.
