Said to have been built by Edward Baynton temp Henry VIII from the ruins of Devizes Castle, the house was destroyed in 1645. Only a fragment survived in 1859, the site occupyed by Bromham House Farm. A rampart of earth called The Battery surrounded the buildings and fishponds named The Moats appear on the 1843 Tithe Map. The gatehouse in Spye Park, Spye Arch, is said to have been either the original gatehouse of Bronham house or built in the 17th century from the debris. The Rev J Skinner visited the site in 1819 and was shown the earthworks and an underground passage, probably a drain, 6ft high crossing the farm garden. He dug in Daffies Patch, the old garden of the mansion where there was a small enclosure and found several sherds of coarse British pottery. A deerpark at Bromham is mentioned in 1583. Field investigation in 1968 found the earthworks depicted on the 1960 Ordnance Survey 6 map to have been destroyed.
