C20 Cymru

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.

Ffurfiwyd yn Hydref 2020, mae Cymdeithas C20 yng Nghymru yn cynrychioli’r dreftadaeth adeiledig gyfoethog ac unigryw o genedl Cymru. Gan weithio mewn fframwaith cyfreithiol penodol i system dreftadaeth sydd wedi’i datganoli i Lywodraeth Cymru, rydyn ni’n cefnogi’r Gymdeithas C20 gyda gwybodaeth am adeiladau nodedig a gwaith achos posibl ledled Cymru.

Gyda llawer o adeiladau pwysig eisoes ar goll, neu’n agos i fod ar goll (gan gynnwys Ffatri Rwber Brynmawr, Ysgol Uwchradd Bettws a Tŷ Darlledu BBC Llandaf) a heb lawer o asedau C20 sydd â diogelwch statudol, rydym yn creu rhwydwaith o unigolion a sefydliadau ledled Cymru i ddod â nhw ynghyd gwybodaeth am ein hadeiladau pwysicaf a’r rhai sydd fwyaf mewn perygl.

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.

Rôl Statudol

Ym mis Hydref 2022, apwyntiwyd C20 Cymru yn ymgynghorydd statudol yng Nghymru gan Cadw, sef y corff treftadaeth genedlaethol Gymreig. Mae hyn yn unol â’r rôl gyferbyniol sydd gan y Gymdeithas yn Lloegr ers 2005. Mae’n ofynnol ar bob awdurdod lleol Cymreig bellach i hysbysu’r Gymdeithas o unrhyw geisiadau cynllunio ar gyfer adeiladau rhestredig a dymchweliadau, gan ein helpu i gynnal mwy o’n treftadaeth bensaernïol fodern ledled y wlad.
