Monnow Bridge in Monmouth is the only remaining fortified river bridge in Great Britain with its gate tower standing on the bridge. Such bridge towers were common across Europe from medieval times, but many were destroyed due to urban expansion.
According to the local tradition, construction of Monnow Bridge began in 1272 to replace a 12th-century Norman timber bridge. Through the medieval era, the English Civil War, and the Chartist uprising, the bridge played a significant, if ineffectual, role in defending Monmouth. It also served as a gaol, a munitions store, a lodge, an advertising hoarding, a focus for celebrations and, most significantly, as a toll gate. Much of the medieval development of Monmouth was funded by the taxes and tolls the borough was entitled to raise through royal charter. The tolls were collected through control of the points of entry to the town, including the gatehouse on Monnow Bridge.
Built predominantly of Old Red Sandstone, the bridge was the subject of significant reconstruction and rebuilding in the 18th and 19th centuries. In those centuries, it also became a popular subject for artists; Turner, Gastineau and Cotman produced sketches of the bridge and gate. In the 20th century, it suffered increasing damage as higher volumes of traffic and the use of ever-larger vehicles led to several serious accidents. In the 21st century, the construction of a new road crossing to the south enabled the pedestrianisation of the bridge.

Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
