What is "overmonnow"

Overmonnow is that part of the town of Monmouth, in Wales, which is located to the west of the River Monnow and the Monnow Bridge. It developed as a suburb of the town in the Middle Ages, when it was protected by a defensive ditch, the Clawdd-du or "Black Dyke", the remains of which are now protected as an ancient monument. In later centuries the area became known as "Little Monmouth" or "Cappers' Town". Development of the area has continued, particularly since the mid-twentieth century, and the area is now a ward of Monmouthshire County Council.
