This is a mural honouring the victims of the tragic fire at Grenfell Tower in London in 2017. The chosen wall features green leaves and a heart bearing the word ‘GRENFELL’, which is a common symbol and tribute in the London borough of North Kensington. The artist is unknown, but the small, pixelated alien in the top left-hand corner is an official work by the world-famous French urban artist Invader. The mosaic (with the location name LDN_21) had been there since 1999—long before the mural beneath it was created. When the Grenfell tribute was installed, this historic mosaic was deliberately left intact.
