This week on Dezeen, British-Ghanaian architect David Adjaye was named the 2021 recipient of the RIBA Royal Gold Medal, while this year's Stirling Prize was cancelled.

Adjaye was the first black architect to win the prize, which is personally approved by the Queen and one of the highest honours in architecture.

"David's contribution to architecture and design globally is already astounding, and I am excited that we have so much more of it to look forward to," said RIBA president Alan Jones.

To celebrate Adjaye's award we looked back at his most interesting projects, which include a crimson-coloured contemporary art centre in Texas, the Smithsonian National Museum of African American History and Culture and Dirty House in London.

This week, RIBA also announced that this year's Stirling Prize was cancelled due to "ongoing public health concerns" over in-person judging. This means that 2020 will be the first year the prize has not been awarded since its inception in 1996.
