Allt-y-Bela in Llangwm, Monmouthshire, Wales, is a house of late medieval origin with additions from the sixteenth to the twenty-first centuries. During the early seventeenth century, it was owned by Roger Edwards, a wealthy Midlands merchant and the founder of Usk Grammar School. Edwards made significant alterations in the Renaissance style to the medieval cruck house. By the twentieth century, the house was in ruins until restored by the Spitalfields Historic Buildings Trust in the early twenty-first century. Now owned by the garden designer Arne Maynard, the house is a Grade II* listed building recognising its significance as an "exceptionally important sub-medieval house with ambitious early renaissance additions".
