Formed in Autumn 2020, C20 Cymru covers the rich and unique twentieth and twenty first century built heritage of the Welsh nation. Working within a distinct legal framework of a heritage system devolved to the Welsh Government, we support the national C20 Society with information about notable buildings and potential casework across Wales.

With many important buildings already lost or threatened (including the Brynmawr Rubber Factory, Bettws High School and BBC Broadcasting House Llandaff) and few C20 assets with legal protection, we are creating a Wales-wide network of individuals and organisations to bring together information about our most significant buildings and those most at risk.

Statutory Role

In October 2022, C20 was appointed as a statutory consultee in Wales by Cadw, the Welsh national heritage body. This mirrors the role the Society has held in England since 2005. All Welsh local authorities are now formally required to notify the Society of any planning applications for listed building consent and demolition, ultimately helping us to preserve more of our modern architectural and design heritage across the nation.
