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.
