Brogyntyn, or Porkington, is a mansion in the parish of Selatyn to the north-west of Oswestry in Shropshire, England. Brogyntyn Hall was the home of the Ormsby-Gore family from 1815, and had previously been the estate of their ancestors the Maurices and Owens since the sixteenth century. It was abandoned and uninhabited from around 1985.
It was a residence of members of the princely dynasty of the Welsh kingdom of Powys and one of the taî'r uchelwyr (houses of the gentry) in late medieval Wales. It subsequently came into the possession of the Ormsby-Gore family (Lord Harlech). Its English correspondent is sometimes given as Porkington. A manuscript known to have been in the possession of Brogyntyn in 1574 was a copy of the Hanes Gruf(f)udd ab Cynan. The house itself is of brick dating from circa 1730 refaced and much added to between 1813–20 by the architect Benjamin Gummow. It is noted for a portico of four giant unfluted Ionic columns with scrolls and pediment. Outside can be seen an arch with 2 pairs of unfluted Ionic columns. In the entrance hall survives an elaborately carved fireplace dated 1617.
Brogyntyn Hall and its 1,445-acre estate, was sold by the 6th and present Baron Harlech in 2001 for less than £5m to a local developer, who divided up the estate, and investigated the potential for a retirement community development in and around the Hall. However, the Hall and 234 acres went up for sale for £5m in December 2013.
