The centre when I was younger was run by the Boys Clubs of Wales and I believe was the national centre . It was used by groups of boys and young men in particular who were associated and affiliated to the National Federation of Boys Clubs .
I went there on many occasions throughout the late 70s and the 80s either as a member of the Avon Boys Club in Bristol , a member of the Avon Group of the National Boys Club or to help run events for various clubs inc . weekly breaks for lads who were fostered or had been in trouble with the authorities .
The centre had football pitches , and outdoor adventure / assault course an indoor gym , dorms , small church , various rooms / halls for meetings etc.. and access to a variety of events of site .
The centre from memory in my time was run by a fantastic little chap named Alwyn Morgan .
Never a dull moment with Alwyn around , very jovial and ran a very professional centre .
Great days .
