Newton House, built in 1660, is part of the Dinefwr Estate. The house now has a Victorian facade and it was in 1775, at the time of the creation of the 1st Baron, that the grounds were remodelled by Capability Brown.

This view shows the front of the house, including the Grand Central Porch, from the entrance gateway.

The Name Dinefwr is pronounced 'Dinever'.

Although the present Newton House dates back to 1660 the house has substantial 18th century and Victorian Gothic additions.

Sold in 1974 it fell into near ruinous disrepair and was occupied by squatters for many years being stripped of many of its original features but both the mediaeval castle and Newton House have been restored by Cadw and the National Trust respectively, who now run the park, its buildings and a tea shop.

There is a small formal garden at the back of the house overlooking the parkland beyond.

Within the Dinefwr Estate there is also a medieval castle. Dinefwr Castle is an imposing ruin as you can see here.

A precise building date is not available but the first castle is said to have been built in the 9th Century but the current castle was probably built a few hundred years later. Unlike many Welsh castles this one appears to have been built by the Welsh and not the Normans.

This shows the substantial outer wall seen from near the Main Keep. It is possible to walk along the sections of wall shown in this photograph.
