In this week's Country Focus Gilbert John visits just some of the 1,200 listed buildings which are an important part of the Pembrokeshire Coast National Park's landscape.

The great buildings include castles and a cathedral but Gilbert concentrates on the smaller buildings. Enthusiasts are helping to restore an old windmill.

An Edwardian pumping station which supplied a castle is now back in action and a monastery has now become a campsite for scouts from all over the UK.
