The Sowley ironworks were completed in the 1590s by the Earl of Southampton. It had a tenuous existence during the 17th century, but with the rapid expansion of Portsmouth dockyard the works were taken over by Henry Corbett, a specialist blacksmith from London, who set up a forge at Beaulieu in conjunction with Sowley. He was financed by Edmund Dummer, a former surveyor of the Navy, and naval contracts for wrought iron followed. Corbett died in 1708 and Dummer continued the business until 1712 when he went bankrupt and his brother Thomas (an ex-navy purser) continued to supply the navy until 1716. By the 1790s, the ironworks were leased by Charles Pocock who lived at the adjacent Sowley House but the ironworks became uneconomic and ceased operating after the Napoleonic Wars. The forge continued to operate until about 1822.
