Have you ever wondered what those small kiosk are on many street corners in Spain, and why there are people inside them selling tickets? Here's what you need to know about 'La ONCE'.

Find a small kiosk with green and yellow writing on, then walk 10 minutes down the road and you’ll see another one – they’re everywhere, especially in big cities.

When they’re open, there’s usually a person sitting inside and sometimes you’ll see people queuing at them too.

These are the ONCE cabins for the Spanish National Organisation of the Blind (Organización Nacional de Ciegos Españoles).

ONCE is a non-profit foundation and charity which aims to improve the quality of life of blind people, those with reduced vision and other disabilities.
