Cadw's description

On the W side of Glynneath, reached by a drive NW off the B4242.

Neuadd Pergwm was celebrated by bards in the C15-16, and was owned from c. 1560 by the Williams family formerly of Blaen Baglan. The house had a central pediment and crenellations in the mid C19 before large additions were made in 1876 for M. S. Williams who added a new front range with neo-Elizabethan detail and long gallery on top floor. Leased to the National Coal Board who mined in the park, abandoned and derelict, the roofs and upper floor collapsed.
