The next Fourth Plinth project

Katharina Fritsch’s big blue bird, Hahn/Cock, which has occupied Trafalgar Square’s fourth plinth since July, will be a tough act to follow. Maquettes of the six works by artists on the shortlist to replace it went on show today, 25 September, in the St Martin-in-the-Fields church nearby, and will remain on view until 17 November.
