Croft-Y-Bwla
is a country house and farm north-west of Monmouth, south-east Wales. The house was built around 1830 and was designed by the noted Monmouth architect George Vaughan Maddox. It has been listed as Grade II since 1974.
Part of the estate is being developed for housing, under the name Parc Glyndwr. During archaeological investigations in advance of development, excavations revealed the remains of a Neolithic crannog built on a man-made island away from the shore of a now-vanished lake, as well as evidence of a Bronze Age boatbuilding community on the site.
