Glamorous landlords! One of Blackfen’s farms, on the east side of Days Lane, was owned from the early 1800s by the Townshends, including the politician John Robert Townshend, 3rd Viscount and later 1st Earl Sydney. The family also owned fields in what is now the Boundary Road area. They lived at Scadbury in Chislehurst and later at Frognal House. All the land was sold off as part of the vast Frognal and Scadbury estate in September 1915.
Each year there is an Open Weekend at Scadbury. You can see excavations of the ruined remains of the medieval manor house and moat, plus WWII defences. There is a self-guided tour of the site and there is a bookstall and refreshments. It takes place this year on 15 and 16 September 2pm-4.30pm. Well worth a visit. http://www.odas.org.uk/open-weekend/
