The small town of Monmouth (pop. 7,500), lies on the confluence of the Monrow and Wye, and has the ruins of a medieval castle, as well as the country's only bridgehouse, which has survived from the 13th century. The Nelson collection in the town museum was started by Lady Llangatock, the mother of Charles Stewart Rolls, the flying pioneer and
founder of the Rolls-Royce works who was born in Monmouth. Rolls also achieved the first non-stop return flight across the English Channel in 1910. A monument in Agincourt Square reflects the pride the town feels about its famous son.
