Architectural evidence suggests that this building dates in part from the 16th century though there appears to be no written evidence for it before c.1600.
Today the building is a pub in the rural area south of Cwmbrân, with views across the valley to the east. The pub sign accurately depicts the meaning of Castell-y-bwch – “the buck’s castle”. However, there is no evidence of a castle here. The name is likely to be fanciful, and perhaps a suitable one, for a large house located in countryside where deer were once common.
The antiquarian John David Rhys claimed that Castell-y-bwch was the home of a giant called ‘Bwch’!
