Mae’r gwaith yn ymdrech dros dro i rwystro waliau’r Castell, yn ogystal â’r ffug-dyrau a’r twneli Fictorianaidd, rhag cwympo ymhellach, tan y gall Ymddiriedolaeth Cadwraeth Castell Rhuthun ddatblygu prosiect cadwraeth uchelgeisiol mawr a gwaith mynediad i’r cyhoedd. Gan bod yr adfeilion yn fregus mae’r gwaith yn cael ei wneud gan gontractwyr arbenigol ar raffau, ac maent wedi clirio llawer iawn o lysdyfiant trwm o’r waliau, gan ddatgelu’r heneb anhygoel hwn am y tro cyntaf mewn degawdau.  Mae’r gwaith wedi dechrau ar sefydlogi, cynnal, a rhwymo’r waliau sy’n dadfeilio i gadw cymaint â phosib o’r gwaith carreg.
The work is a holding measure to prevent further collapse of the Castle walls and the fascinating Victorian follies and tunnels built onto and within them until the recently formed Ruthin Castle Conservation Trust is able to develop an ambitious project for their large scale conservation and public access. Due to the fragile state of the ruins the work is all being undertaken by specialist rope access contractors who have cleared a huge amount of heavy vegetation from the walls, revealing this spectacular monument in its full glory for the first time in decades. Work has now begun pinning, propping, shoring and strapping the crumbling walls to stabilise as much masonry as possible.
