Tollgate House, Mitchel Troy

Monmouth Troy was one of the two former railway stations at Monmouth. It was built in 1857 by the Coleford, Monmouth, Usk and Pontypool Railway and was used by several other branch lines as the local rail network expanded. The station closed in January 1964 following the closure of the last two lines to the station, the Wye Valley Railway and the Ross and Monmouth Railway.

Troy House is a Welsh historic house, on a "ducal" scale, north-east of Mitchel Troy, Monmouthshire. The original house belonged to Blanche Herbert, Lady Troy, of the Herbert family of Raglan Castle, who owned great estates in South Wales as Marquesses of Worcester and later Dukes of Beaufort. The present structure, overlooking the River Trothy was constructed from 1681 to 1684 as a wedding present for Charles Somerset by his father, Henry Somerset, 1st Duke of Beaufort. Troy House is a Grade II* listed building and its gardens and park are listed, also at Grade II*, on the Cadw/ICOMOS Register of Parks and Gardens of Special Historic Interest in Wales.

Monmouth Troy Goods Yard was a large goods yard near Monmouth Troy railway station in Monmouth, Wales. It was opened in 1857 by the Coleford, Monmouth, Usk and Pontypool Railway at the same time as the station. As other railways reached Monmouth Troy the goods yard grew in importance. At its height, the goods yard was used by the Wye Valley Railway, Coleford Railway, Ross and Monmouth Railway as well as the Coleford, Monmouth, Usk and Pontypool Railway. The goods yard closed in 1964 when the last two railways, the former Wye Valley Railway and Ross and Monmouth Railway, closed. The non-rail depot remained open until October 1964.

The Clawdd-du, also known in historical records as the Black Dyke, Black Ditch or Clawthy, is a mediaeval linear defensive earthwork or moat, constructed as protection for the faubourg of Overmonnow, on the opposite side of the River Monnow from the town and castle of Monmouth, Wales.

The River Monnow (Welsh: Afon Mynwy) marks the England–Wales border for much of its 42 miles (68 km) length. After flowing through southwest Herefordshire, England, and eastern Monmouthshire, Wales, its confluence with the River Wye is approximately 1⁄3 mile (0.54 km) south of Monmouth. The Monnow rises near Craswall on Cefn Hill just below the high Black Mountains, Wales. It flows southwards, gaining the waters of its tributaries the Escley Brook and Olchon Brook near Clodock and the waters of the River Honddu, from the Welsh side of the Black Mountains, near Pandy. The river then flows briefly eastwards, to Pontrilas, where it is joined by its largest tributary, the River Dore before again turning southwards. At Monmouth, the Monnow joins into the River Wye with the River Trothy. The unique medieval Monnow Bridge in Monmouth is the only remaining fortified river bridge in Great Britain with its gate tower standing on the bridge. The 40 miles (64 km) long-distance Monnow Valley Walk follows the river.

The Riverside Hotel is a public house and hotel located in Cinderhill Street, Monmouth, Wales. The hotel has a bar and a function room and has 17 bedrooms.

The Church of St Thomas the Martyr at Overmonnow, Monmouth, south east Wales, is located beside the medieval Monnow Bridge across the River Monnow. At least part of the building dates from around 1180, and it has a fine 12th-century Norman chancel arch, though the exterior was largely rebuilt in the early 19th century. It is one of 24 buildings on the Monmouth Heritage Trail and is a Grade II* listed building.

The Cross is situated in St Thomas' Square, Overmonnow, Monmouth, Wales, in the middle of a roundabout opposite the Church of St Thomas the Martyr and the western end of the Monnow Bridge. Originally mediaeval, and also known as Overmonnow Cross, the cross was reconstructed in 1888 and has been classed as a Grade II listed structure since 15 August 1974.

Overmonnow is a suburb of the town of Monmouth, in Wales, which is located to the west of the River Monnow and the Monnow Bridge. It developed 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".

The Green Dragon is a public house and inn located in St Thomas Square Monmouth, Wales. The pub provides live music on weekend evenings and during the annual Monmouth Festival the pub is used as a venue for entertainment.

Monnow Bridge (Welsh: Pont Trefynwy Welsh pronunciation: [pɔnt tre:vənʊɨ]), in Monmouth, Wales, 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, diminishing defensive requirements and the increasing demands of traffic and trade. The historical and architectural importance of the bridge and its rarity are reflected in its status as a scheduled monument and a Grade I listed building. The bridge crosses the River Monnow (Afon Mynwy) 500 metres (1,600 ft) above its confluence with the River Wye. Monmouth had been a significant border settlement since the Roman occupation of Britain, when it was the site of the fort of Blestium. The River Wye may have been bridged at this time but the Monnow, being easily fordable, appears not to have had a crossing until after the Norman Conquest. 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.

Blestium (also Blestio in the Antonine Itinerary (Iter XIII)) was a small fort and iron working centre in the Roman province of Britannia Superior, part of Roman Britain. It has been identified with the site of the later town of Monmouth in south east Wales, located adjoining the confluence of the River Monnow with the River Wye. A plaque on the local bank records its position.
