A gunpowder plant had been established around 1573 in Faversham. The town had a stream which could be dammed at intervals to provide power for watermills. It became known as the Home Works in the 18th century and was nationalised in 1759. By the 19th century, the site stretched for around a mile along the waterfront. A second explosive works was established at Oare to the northwest of town in the late 17th century, with the Marsh Works following in 1786. Towards the end of the 19th century, two new factories were built alongside the Swale to manage production of TNT and cordite. Faversham developed six explosive factories, and from 1874 to 1919, the town was the centre of the explosives industry in the UK.
