The Clermont State Historic Site, also known as the Clermont estate, the Clermont Manor or just Clermont, is a New York State Historic Site in southwestern Columbia County, New York, United States. It protects the former estate of the Livingston family, seven generations of whom lived on the site over more than two centuries. History The name Clermont derives from "clear mountain" in French and was inspired by the view of the Catskill Mountains across the Hudson River from the estate. The estate was established by Robert Livingston of the famous Livingston family following the death of his father, the first Lord of Livingston Manor, in 1728; while most of the manor was inherited by the eldest son Philip Livingston, in the southwest corner, later named Clermont, was willed to Robert. The original house was built about 1740. Robert Livingston of Clermont died on June 27, 1775, and the estate passed to his son, Robert, who was known as 'Judge Livingston' to distinguish him from his father. Judge Livingston was a member of the New York General Assembly from 1759 to 1768, served as judge of the admiralty court from 1760 to 1763 and was a delegate to the Stamp Act Congress of 1765. He married Margaret Beekman, daughter of Colonel Henry Beekman. Their son, Robert R. Livingston, later known as "Chancellor", was a Founding Father of the United States and served on the Committee of Five that drafted the United States Declaration of Independence. Judge Robert died about six months after his father, on December 9, 1775. Burning and rebuilding In October 1777, British ships sailed upriver from New York City in support of General John Burgoyne who was north of Albany. That same force had already stormed two forts in the Hudson Highlands and burned Kingston, New York. Major General John Vaughan led a raiding party to Clermont and burned Livingston's home because of the family's role in the rebellion. Margaret Beekman Livingston rebuilt the family home between 1779 and 1782. Robert R. Livingston became the estate's most prominent resident. Chancellor Livingston administered the oath of office to President George Washington, became Secretary of Foreign Affairs, and negotiated the Louisiana Purchase. In 1793, Robert Livingston built a second mansion on the property—confusingly named "Clermont", it subsequently became known as both "Arryl House" and "Idele"—which burned in 1909. The ruins of that house are still visible at the south
