Monmouth sits where the Monnow meets the Wye. This border town has deep roots in the past. My top tip is to walk across the Monnow Bridge. You can see the stone gatehouse for free. It is a prime choice for a low cost look at history. The bridge is the only one of its kind in Britain. In the heart of the town sits Agincourt Square. You can see the statue of Henry V near the Shire Hall. The streets are full of local shops and stone walls. Walk to the top of the Kymin for fresh air and wide views. The air is fresh and the paths are quiet. It is a smart spot for a trip.
