Mae byrddau iechyd wedi addasu adeiladau sy'n bodoli eisoes, gan gynnwys Stadiwm y Principality, parc gwyliau a stiwdio deledu hyd yn oed, er mwyn darparu 6,000 o welyau ychwanegol.
Health boards have repurposed existing buildings, including the Principality Stadium, a holiday park and even a television studio to provide an additional 6,000 beds.
