CADW: Welsh Historic Monuments is the organization that has the responsibility for protecting, conserving and presenting ancient monuments and historic buildings in Wales. They also perform archaeological excavations. During summer months events are presented at some of the larger castles.
The name Cadw comes from the Welsh word that means "to keep" or "to preserve". Cadw cares for over 100 prehistoric sites, castles, Roman sites, ecclesiastical buildings, parks and gardens, and historic buildings of national importance, which are open to the public.
If you are visiting Wales, you'll want to join. Membership provides you entry to the sites at a fraction of what it would cost to pay to visit each separately. With membership you get a guidebook and map/gazetteer to all the sites and a list of annual events. Even if you're not visiting, you may want to join to support their efforts.
Cadw prints a range of publications, each meticulously researched. They can be purchased when visiting the sites or by mail order from the address below. More details from their website http://cadw.wales.gov.uk.
To join from the UK call Freephone 0800 0743121. Membership is available at a lower rate for Welsh residents under 16 or over 60.
