Brogyntyn Hall

This derelict mansion near Oswestry was built in 1730 and owned by Lord Harlech's dynasty (of Harlech Castle and Harlech T.V. fame) for many years until it was sold for financial reasons.
It was the main BT telephone exchange and used in WW2 for communications for the spy network in Europe.
It is now in disrepair after being empty for 15 years and is up for sale together with acres of parkland for £5,000,000 if anyone has a bit of spare cash!
