Among the designs of the leading British-Ghanaian architect Sir David Adjaye OBE are the Smithsonian National Museum of African American History and Culture in Washington DC, which opened in 2016 in a ceremony led by the then US President Barack Obama, and the planned UK Holocaust Memorial and Learning Centre next to the Palace of Westminster in London.

David Adjaye is in Venice ahead of the opening of his Ghana Pavilion for this year's Biennale, and in a rare interview the architect discusses the role of architecture and the importance of anthropology and ethnography in his designs.
