It is situated about 2 miles (3.2 km) from the Newport to Cardiff road, near a Roman fort, which gave the name to the estate. The Gaer Hillfort (alternative: the Gollars), a large circular site, is a huge fort situated in a defensive position overlooking the Ebbw River. It contains many enclosures, a large bank and a ditch. In the 17th century, the hillfort was included in the ornamental landscaping plan of nearby Tredegar House.The original Gaer House was built in the reign of Queen Elizabeth by Alexander Seys, Esq., second son of Roger Seys, Esq., of Boverton. Roger Seys was Attorney-general of Wales in the time of Queen Elizabeth. Alexander Seys had several children by his wife Elizabeth: Roger, Alexander, William, Elizabeth, Mary, and Florence. The Gaer House passed to the third son, William. The Gaer remained in the Seys family until the death of William Seys, High Sheriff for the county in 1738. He left four daughters, his coheirs. Florence, his third daughter, married Henry Montonnier Hawkins (d. May 1814), and the house passed to their son, Anthony Montonnier Hawkins in whose lifetime, the Gaer House was entirely renovated, the Elizabethan architecture destroyed, and a modern front substituted without any particular style of architecture. It stands upon a slight topographic prominence, which has views over the Bristol Channel to the coast of Somersetshire. In one area, the grounds extend to Tredegar House Country Park, on the highest portion of which are the remains of the Roman fort or encampment.By the mid 19th century, it was the home of Thomas Powell, a Magistrate and Deputy-Lieutenant of Monmouthshire, whose colliery was named the Gelly Gaer. Charles D. Phillips (1845–1912) owned the house in the early 20th century. He was apprenticed as a young man to the mechanical engineering profession, and became proprietor of an engineering business. He went on to own the Emlyn Works at Newport, along with works at Gloucester, which and branches in London and Cardiff. He also founded and published Phillips' Monthly Machinery Register, to which he added later an electrical and autocar supplement.

White Castle (Welsh: Castell Gwyn), also known historically as Llantilio Castle, is a ruined castle near the village of Llantilio Crossenny in Monmouthshire, Wales. The fortification was established by the Normans in the wake of the invasion of England in 1066, to protect the route from Wales to Hereford. Possibly commissioned by William fitz Osbern, the Earl of Hereford, it comprised three large earthworks with timber defences. In 1135, a major Welsh revolt took place and in response King Stephen brought together White Castle and its sister fortifications of Grosmont and Skenfrith to form a lordship known as the "Three Castles", which continued to play a role in defending the region from Welsh attack for several centuries. King John gave the castle to a powerful royal official, Hubert de Burgh, in 1201. Over the next few decades, it passed back and forth between several owners, as Hubert, the rival de Braose family, and the Crown took control of the property. During this period, White Castle was substantially rebuilt, with stone curtain walls, mural towers and gatehouses, forming what the historian Paul Remfry considers to be "a masterpiece of military engineering". In 1267 it was granted to Edmund, the Earl of Lancaster, and remained in the hands of the earldom, and later duchy, of Lancaster until 1825. Edward I's conquest of Wales in 1282 removed much of White Castle's military utility, and by the 16th century it had fallen into disuse and ruin. The castle was placed into the care of the state in 1922, and is now managed by Cadw, the Welsh heritage agency.
