Monmouth ( , ; meaning "town on the Monnow") is a town and community in Wales. It is situated where the River Monnow joins the River Wye, from the Wales–England border. Monmouth is northeast of Cardiff, and west of London. It is within the Monmouthshire local authority, and the parliamentary constituency of Monmouth. The population in the 2011 census was 10,508, rising from 8,877 in 2001. Monmouth is the historic county town of Monmouthshire although Abergavenny is now the county town. The town was the site of a small Roman fort, Blestium, and became established after the Normans built Monmouth Castle . The medieval stone gated bridge is the only one of its type remaining in Britain. The castle later came into the possession of the House of Lancaster, and was the birthplace of King Henry V in 1386. In 1536, it became the county town of Monmouthshire. A market town and a focus of educational and cultural activities for the surrounding rural area, Monmouth has become a tourism centre at the heart of the Wye Valley. Etymology The name Monmouth is an English contraction of 'Monnow-mouth'. The Welsh name for the river, Mynwy, which may originally have meant "fast-flowing", was anglicised as Monnow. The town was originally known in Welsh as Abermynwy ("mouth of the Monnow"), replaced by Trefynwy ("Monnow town" – the initial m of Mynwy mutating in Welsh to f pronounced /v/) by the 1600s. History Excavations undertaken by the Monmouth Archaeological Society on sites along Monnow Street have uncovered details of the early history of the town. The Council for British Archaeology has designated Monmouth as one of the top ten towns in Britain for archaeology. Prehistoric Evidence of a Bronze Age boat building community, including three long channels adjoining the site of a now-vanished lake, was discovered in September 2013, during archaeological investigations by the Monmouth Archaeological Society of the Parc Glyndwr housing development site, immediately north-west of the town. The excavations later revealed the remains of a Neolithic dwelling. The dwelling was constructed on stilts on a human-made island away from the lake shore in water up to deep. Oak timbers had been "skillfully" cut with stone or flint axes to form stilts, of posts and poles, which "probably" rested on three parallel fully-grown tree 'sleeper beams', up to wide, laid horizontally on the lakebed. Timbers from the structure were radiocarbon dated to 4867
