The former neo-Gothic Early English style parish church of All Saints, built in 1838 by George Wyndham, 4th Earl of Egremont, lord of the manor, who also built Blackborough House[1] was demolished in 1994, having become structurally unsafe.

The churchyard however is still maintained and the ecclesiastical parish and parochial church council still exist.

[12] The arms of "Cobham of Blackburgh Bolhay" are recorded by Pole as Gules, on a chevron or three eagles displayed sable,[11] which are a difference of the arms of the prominent family of Cobham of Cobham Hall in Kent, created Baron Cobham in 1313: Gules, on a chevron or three lions rampant sable, the heir of which family was Sir Thomas III Brooke (died 1439) of Holdich and Weycroft, Devon, grandson of Sir Thomas II Brooke (died 1418) of Holditch (whose monumental brass, together with that of his wife Joan Hanham, survives in Thorncombe Church), "by far the largest landowner in Somerset"[13] and served 13 times as a Member of Parliament for Somerset.

Originally designed as an Italianate palace, there were no funds to complete it on this scale, so it was constructed as two smaller, linked buildings.

[16] The house was variously used as a school, a religious institution for wayfarers and for training conscientious objectors for relief work[17] As of 2016, the house is semi-derelict but has been purchased by a developer who plans to restore it and turn it into an events venue.
