The newly unveiled sculpture on Trafalgar Square's Fourth Plinth, titled 'Mil Veces un Instante (A Thousand Times in an Instant)', features 726 plaster casts of transgender and non-binary individuals, created by Mexican artist Teresa Margolles. This installation, which pays tribute to the marginalized trans community and the memory of Karla La Borrada, a trans woman who was murdered in 2015, aims to highlight ongoing violence and discrimination faced by these groups worldwide. The casts are arranged in the form of a tzompantli, a traditional Mesoamerican skull rack, symbolizing both loss and resilience. Made from plaster, the artwork is designed to decay over time, reflecting the impermanence of life and the ongoing struggle for rights. Margolles emphasized that the work serves as both a memorial and a call to action for future generations to live with dignity. The installation will be present until 2026, marking a significant addition to the series of temporary artworks displayed at this historical site since 1999.
