Municipal Murals

I'd often pondered the fate of the ceramic mural on the vacant GPO building, Farringdon Road, though it wasn't until seeing the wall relief on Bexhill's 1970s Sainsbury's that I hoped someone was forming an archive. Luckily, The Twentieth Century Society is targeting those features caught perilously between reappraisal and redevelopment and campaigning for their preservation. While the modernising thrust for constant renewal, admittedly, shapes the future's curios, the UK's recent architectural history (with its faint whiff of civic hope) can't be entirely without lessons for our lives here in C21.

• Works pictured are the innovations of William Mitchell and form part of a staggering online archive. The site also outlines technical innovations and the groundbreaking use of materials employed in often gargantuan projects.
