Children at Priory Street Nursery in York helped celebrate its 20th birthday this year at a special party.

There was a big cheer for devoted nursery assistant Caroline Clarkson, who has been at the school since its opening. Manager Erica Birkitt paid tribute to Caroline's hard work.

The nursery is run by York's Council for Voluntary Services. It has room for up to 30 children, aged between six months and five-years-old, and takes 18 per session.
