Controversy erupted after the third episode aired. In it, a group photo of six architects was Photoshopped to remove Patty Hopkins, the one woman present. The mini-series focuses on the five men included in the image, with Hopkins making an appearance only in the first episode. A RIBA exhibition tied in with the series does include Hopkins, explain Richard Waite and Laura Mark.
The BBC dismissed the accusations, pointing out that the series does not attempt a comprehensive history of British architecture.
