Tredegar House (is a 17th-century Charles II-era mansion. For over five hundred years it was home to the Morgan family, later Lords Tredegar; one of the most powerful and influential families in the area. The mansion stands in a reduced landscaped garden forming the non-residential part of Tredegar Park.
The earliest surviving part of the building dates back to the late 15th century. The house was originally built of stone and had sufficient status to host Charles I. Between 1664 and 1672, however, William Morgan decided to rebuild the house on a larger scale from red brick, at that time a rare building material in Wales.
In 2011 the National Trust signed an agreement with Newport City Council to take on the management of the building, as well as the 90 acres of gardens and parkland. The National Trust provide free-flow access to the house, but have closed parts of the upstairs to the public.
References:The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
