The 15th commission in Mayor of London’s Fourth Plinth programme has been unveiled in Trafalgar Square.

Artist Teresa Margolles’ Mil Veces un Instante (A thousand times an Instant) is made up of plaster casts of the faces of 726 trans, non-binary, and gender non-conforming people which were made in Mexico City and Juárez, Mexico; and London. 

The casts – which Margolles spent more than 1,000 hours making – were created by applying plaster directly onto the faces of participants, meaning the plaster is infused with their hair and skin cells.

The next artworks to grace the Fourth Plinth will be Tschabalala Self’s Lady in Blue – a bronze work patinated with Lapis Lazuli blue which will be installed in 2026 – and Andra Ursuţa’s Untitled – a shrouded equestrian statue which will be installed from 2028.

Mil Veces un Instante replaced Samson Kambalu’s Antelope which had been on the Fourth Plinth since 2022.
