"Mae caer Porth y Rhaw yn safle pwysig sy'n gallu dweud llawer wrthym am fywyd yn yr Oes Haearn a’r Cyfnod Rhufeinig yn Sir Benfro.  Mae gwaith blaenorol wedi dangos i ni y gallai'r gaer fod wedi cael ei defnyddio ers dros fil o flynyddoedd. Y tu fewn iddo, mae olion tai crwn cynhanesyddol i’w gweld, ac roedd rhai ohonynt wedi'u hailadeiladu sawl gwaith.
“Porth y Rhaw fort is an important site which can tell us a lot about life in Iron Age and Roman Pembrokeshire.  Previous work has shown us that the fort may have been used for over a thousand years. Its interior contains the remains of prehistoric roundhouses, some of which had been re-built several times.
