Tradition dates it to 1675, but the form dates most of the surviving house to the first half of the 18th century.","why_significant":"The nomination argues the house is significant as the home of the region's first European settler, Col. Jonathan Tyng. It is also described as one of the finest surviving examples of Georgian architecture in the lower Merrimack River Valley. It is further tied to events and people important to the valley's history, including King Philip's War and the town's founding.","narrative":"Perched on a knoll above the Merrimack River Valley in Tyngsborough, this 2½-story gambrel-roofed house was the home of Col. Jonathan Tyng, the first European settler of the area. Local tradition dates the house to 1675, when Tyng stayed on and fortified his home during King Philip's War while other settlers fled. Structural and stylistic evidence, including the central hall plan, open-string staircase and simple panelling, points instead to the first half of the 18th century for most of the building, with later changes. A monumental Corinthian portico was added in 1910, and the rear arcade is believed to date from the same time. Barns and sheds from the 19th and 20th centuries survive on the grounds, along with a family cemetery. The house was listed for its architecture and for its links to Tyng, who served as selectman, representative and garrison commander, and to the Pawtucket sachem Wannalancet, who spent his last years there.","period_of_significance":"1675","architect_builder":"Col Jonathan Tyng","architectural_style":"Georgian, with a Georgian Revival portico added in 1910","criteria":[],"status_note":"Listed as unoccupied and in good condition, with alterations.
