 The ruined walls of both the Abbey and later mansion were gradually engulfed in quantities of industrial waste.The ownership of the site passed to the Rice family, Barons Dynevor, and it was in the 1920s, under Walter FitzUryan Rice, 7th Baron Dynevor that a local group of amateur archaeologists began the process of uncovering the medieval ruins.The archaeology of the abbey was eventually excavated between 1924 and 1935.
