In the centre of bustling and busy Barcelona there is unusual quiet: just the babble of children playing in a small playground and the sound of the birds.
There is virtually no traffic and the space where cars would have parked is given over to play areas, trees and even a running track.
Superblocks is a radical plan to reclaim the streets from the noise and pollution of traffic, one that could save hundreds of lives that might otherwise be lost because of heavily polluted air. It also hopes to act as a blueprint for other cities.
There are just six superblocks so far, but Barcelona plans hundreds of others. They are made up of nine existing blocks joined together into an area which bans all but essential vehicles – which are limited to 10 kph (6mph). Parking for residents is underground.
