London’s mayoral office has announced six shortlist finalists for the annual Fourth Plinth Commission in Trafalgar Square. 

The candidates for this year’s commission include an international slate of artists vying to be one of two winners that will replace Heather Phillipson’s THE END when it is removed in September of 2022. 

Highlighted by a monument to 850 living trans women and the recreation of an unfinished grain silo Ibrahim Mahama knew as a child in rural Ghana, finalists seeking a shared theme of recollection and memento turned to their past integration of architecture to inform sculptures that, as artist Teresa Margolles told The Guardian, form an active “wall of memory.” 

Other entries include a giant rocket ship meant to inspire future activists at the popular protest site, a jewelry tree sculpture by Nicole Eisenman inspired by Bloody Sunday, a statue based on a 1914 photograph of murdered Malawian revolutionary John Chilembwe, and another sculpture by Paloma Varga Weisz that draws its inspiration from German folklore tradition.

“These proposals from our most international line-up of artists to date shows yet again why the Fourth Plinth is the world’s most high-profile public art prize,” London Mayor Sadiq Khan said in a statement.

The Fourth Plinth was completed in 1841 but remained unfurnished until 1998, when the Royal Society of Art commissioned the first in a series of rotating exhibitions now administered by the Mayor’s culture team.

Winners of this year’s commission will be announced in June and will be featured along with the other shortlisted finalists in an exhibition at London’s National Gallery on view through July 4th.
