A cultural centre familiar to generations of children in Wales is celebrating its 75th anniversary.

The Urdd centre at Llangrannog in Ceredigion, which has recently been refurbished, opened in 1932 to promote Welsh language and culture.
Back then 150 young people took part in the events during a four-week summer camp, but now the centre welcomes more than 25,000 visitors a year.
To mark the occasion, a book based on people's memories is being published.
Events to help celebrate the landmark anniversary are being held on Friday at the centre, and many of those who visited Llangrannog in the 1930s, and the subsequent decades, have been invited.
An early visitor was Gwyn Jones from Cilfynydd, near Pontypridd, who went there aged 14.
"There were hardly any facilities when I went there," he said.
"There were six tents and the rain would find its way in. But there would be concerts and events in the food hall.
The range of activities at Llangrannog have changed since 1932
"I had great fun and that's where I learnt to swim in the sea. It was a place to have fun and meet people from all parts of Wales"
The Urdd said the centre had developed continually over the years, with the tents and cold water taps giving way to en-suite rooms, following a £5.5m transformation of the centre.
The range of activities has also increased, including skiing, quad biking, roller-blading and horse riding.
The Urdd said these developments had ensured the centre's success in being one of the main residential, educational, outdoor activity centres in Britain.
Steffan Jenkins, centre director, said: "Llangrannog Urdd Centre is key to the future of the language and culture in Wales today.
"The centre is also essential to the local community and economy with a workforce of 90 staff at the centre, a turnover of over £2m and a contribution of over £2.5m to the local economy."
