Most walls covered by a mural

At Pachuca, Mexico, 209 building walls were covered by a single mural – El Macro Mural Barrio de Palmitas – when the art collective known as the German Crew painted them in a 20,000-square-metre pattern of bright colours. Completed in 14 months in 2014–15, and working with local residents, the finished design used more than 20,000 litres of paint and – when seen from afar – looks like a vibrant swirled rainbow, with stripes running across several houses.

This was part of a government project called Pachuca Paints Itself. According to director Enrique Gomez, the mural helps unite the community and rehabilitate the local neighbourhood. In total, 452 families and 1,808 people saw their homes transformed.
