Fulton County Courthouse
Also known as: Tryon County Courthouse

Why it's listed
Built in 1772-1773 in the center of Johnstown, New York, this brick courthouse is described as the oldest existing courthouse in the state. It began as the Tryon County Courthouse, and Sir William Johnson pressed for Johnstown to become the county seat and contributed money toward construction. Samuel Fuller, architect of Johnson Hall, is supposed to have designed it. The building is one and one half stories, with Flemish bond brick walls, a bellcast gable roof and an octagonal cupola added in the late eighteenth or early nineteenth century. A porch was added after 1872 and a rear addition around 1900, while the interior has been remodeled into a single courtroom. The first court session met on September 8, 1772. The building later served Montgomery County and, from 1838, Fulton County. Aaron Burr defended Southwick here in 1812, and figures such as Alexander Hamilton and Chancellor Kent are associated with it. It still serves as a courthouse.
Significance in brief: It is described as the oldest existing courthouse in New York State and a Georgian civic building that has changed over the years as expected. It is closely tied to Sir William Johnson, who pushed for Johnstown to be the Tryon County seat, and to judicial events and legal figures such as Aaron Burr, who defended Southwick there in 1812. It has served as the judicial seat of Tryon, Montgomery and, since 1838, Fulton County.

What listing means for this property
For a publicly owned building or structure, listing mainly matters when federal funds, permits or licences are involved: projects then go through Section 106 review so effects on the property are considered. Listing also strengthens applications for preservation grants and, for leased income-producing uses, can enable the federal rehabilitation tax credit.
