The estate of Sandwell, formerly the property ofSandwell Priory, was owned from 1531, shortly after the Dissolution of the Monasteries, by Dame Lucy Clifford; in 1569 they were purchased from her grandson by Robert Whorwood. In 1701 William, Baron Dartmouth purchased the estate of Sandwell from Thomas Brome Whorwood, a descendant of Robert Whorwood. Priory House, created out of the original priory, was known as Sandwell Hall by 1611 when it was occupied by William Whorwood. The Earl of Dartmouth had the house rebuilt, by William Smith of Tettenhall, a leading master-builder of the area. Construction began in 1705, and the brick-built hall, designed by Smith, was completed about 1711. Fragments of the priory house remained as parts of the new building. The house was the favourite residence of William Legge, 2nd Earl of Dartmouth, grandson of the 1st Earl whom he succeeded in 1750. In the mid 18th century a park was created, and ponds, thought to have been part of the priory, were modified. In the early 19th century a portico was added to the house, and the house was extended on the west side. From 1853 William Legge, 5th Earl of Dartmouth lived at Patshull Hall; it is supposed that his move away was due to the industrial development of West Bromwich. Sandwell Hall was let for a short period to the industrialist George Muntz, then was unoccupied.
Later history
In 1857 it became the Sandwell Hall Training Home, established "to receive children, more especially the orphans of the respectable poor, and train them for domestic service". The Earl and Countess of Dartmouth were Presidents of the charity. In 1898 it became a branch of Winson Green Asylum, housing 150 inmates. In 1907 the ReverendHarold Burden and his wife Katherine opened the hall as an Industrial School for Mentally Defective Children, specified in 1908 to accommodate 200 boys. In 1913 the Burdens set up a trust to take over ownership of this and their other institutions. The school closed in 1921. The building, damaged by mining subsidence, was demolished in 1928. The lodge of Sandwell Hall survives, within the roundabout of Junction 1 of the M5 Motorway, at ; it is a Grade II listed building. It is a pedimented gateway with Doric columns, thought to be built by William Smith; a curved flanking wall on its left also survives.
