Bleddfa Castle

Bleddfa Castle (sometimes referred to as Bledeach or Bledvach Castle) was a motte and bailey structure near Llangunllo in modern-day Powys, Wales. It is believed to have been built before 1195 and abandoned by 1304. What remains today is described as a "mutilated oval mound" of 46 by 36 metres (151 ft × 118 ft), containing some traces of masonry. It is surrounded by a rectangular bailey measuring 100 by 60 metres (330 ft × 200 ft), with a hedge on its northern border.^[2]
