The UK’s Houses of Parliament are getting down and dirty—but this time it’s in the name of art. A 50-metre-long translucent latex cast of a wall inside Westminster Hall, the oldest part of the Houses of Parliament, which contains almost a century’s worth of British dust and grime, will hang from the hall ceiling (29 June-1 September). The project is part of artist, architect and conservationist Jorge Otero-Pailos’ ongoing series The Ethics of Dust, which has seen similar casts produced from the Trajan’s Column in London’s Victoria and Albert Museum and the 14th-century Doge’s Palace in Venice (the series considers conservation and cultural responses to pollution). The work, commissioned and produced by Artangel with support from Bloomberg Philanthropies, has involved five years of collaboration with Parliament’s restoration and stone cleaning project. In a statement Caroline Nokes, chair of the speaker’s advisory committee on works of art in Parliament, said that the exhibition “will give the public a new and unique way to consider the many historic events to which [Westminster Hall’s] walls have borne witness". Admission is free but advance tickets must be booked at artangel.org.uk/ethics-of-dust
