Pupils at a Watford primary have celebrated its 40th anniversary.

St Antony's Catholic Primary School, in Croxley View, first opened on June 13, 1974, with just 12 pupils.

Now it has 313, having grown drastically over the last with extensions to the main school and early years building.

To mark the occasion the school held a treasure trail, quizzes,, class parties, an open afternoon, whole school mass, lunchtime picnic and a 1970s day during the week.

The celebrations ended with a family barbecue.
