In accordance with an Enclosure Act of 1770, promoted by the Duchy of Lancaster, the Royal Forest of Knaresborough was enclosed. The enclosure award of 1778 clarified ownership of land in the Harrogate area. Under the award, of land, which included the springs known at that time, were reserved as a public common, The Stray, which has remained public open space. The Enclosure Award facilitated development around the Stray. During the 19th century, the area between High Harrogate and Low Harrogate, which until then had remained separate communities a mile apart, was developed, and what is now the central area of Harrogate was built on high ground overlooking Low Harrogate. An area to the north of the developing town was reserved to the Duchy of Lancaster, and was developed for residential building. To provide entertainment for the increasing numbers of visitors the Georgian Theatre was built in 1788. Bath Hospital (later the Royal Bath Hospital) was built in 1826. The Royal Pump Room was built in 1842. The site of Tewit Well is marked by a dome on the Stray. Other wells can be found in the Valley Gardens and Royal Pump Room museum.
