road. A Roman milestone and a Roman coin hoard were unearthed near Dinefwr Castle, and pieces of amphorae and Samian items have been excavated near Dinefwr Farm. During the 12th century, Dinefwr Castle was built by Lord Rhys, Prince of Wales. The castle and grounds were seized by Henry VIII in 1531, and the estate owners, who changed their family surname to Rice, subsequently had to buy back their property from the Crown. The family were elevated to the peerage of Great Britain as Baron Dynevor. Mary I is documented to have restored some of the land back to the Rhys family, but it was not until the reign of Charles I that the family fully regained their properties. Newton House was originally built during the medieval period at some distance from the castle. It is documented to have been later modified in 1595 and 1603. The current Newton House was completed in 1660 under the command of Edward Rice. In the late 1700s, George Rice and his wife Cecil began the construction of a landscape garden, and hired eminent architect Capability Brown in 1775 to assume responsibility for the development. Turrets and battlements were added between 1760 and 1780, giving the property a more romanticised appearance. During the Rebecca Riots of 1843, Colonel George Rice was awoken one night in September and found an empty grave dug in the grounds, warning him that he would be buried in it by October 10. Newton House fell into a turbulent period after the death of the 7th Baron Dynevor in 1956. His son Charles Arthur Uryan, the 8th Baron, died just six years later, and most of the estate and a number of family's assets had to be sold off to pay duties. In 1974, the property was sold by the current Baron Dynevor, and later fell into disrepair: it was occupied by squatters and thieves who removed beams and furniture. The house, along with Dinefwr Castle, have since been restored by Cadw and the National Trust respectively. The National Trust acquired the deer park in 1987 and Newton House three years later. Architecture Edward Rice ordered the construction of a Jacobean house on the site of an earlier medieval mansion in 1659, and it was completed the following year. Turrets and battlements were added between 1760 and 1780. Though the property remains Jacobean, around 1856, there were significant changes made
