Felicity Evans asks how the valleys of south Wales near Caerphilly have fared since the mines closed. She visits new parklands that have been planted where the collieries once stood.

She begins at Senghenydd, site of two mining disasters just one hundred years ago, one of them the worst ever experienced at a UK mine. Former teacher in the village and now a broadcaster, Roy Noble reflects on the legacy of the disaster, and how it's still remembered even though a primary school has been built on the site of the mine, since the pit was closed nearly 50 years ago.

Felicity also visits two other parks in the Caerphilly area which have been created on the sites of former collieries: Parc Cwm Darran which was planted in the 1980s, and Parc Penallta, which has been developed since the Millennium. How do residents relate now to their local landscape, and the memorials to the industry that once defined the region?
