It sits on a 1.5-acre parcel with a modern garage and gazebo.","why_significant":"The building is a fine regional example of Federal-era civic architecture, built under the direction of William H. Ludlow with bricks from his kiln. It is also tied to the county's first judicial system, where leading New York attorneys practiced and the Harry Croswell libel case began in 1802-1803.","narrative":"Built in 1786, this large brick building in Claverack served as the first Columbia County courthouse until the county seat moved to Hudson in 1805-06. It has five bays across and four deep, two stories, a center hall plan and a stone foundation. William H. Ludlow directed construction and supplied bricks from his own kiln. Later uses changed the building: it became a meeting hall, then a residence around 1843, when Greek Revival features such as the portico, entrance and cornice were added. About 1946 it was divided into apartments, and it still holds dwellings today, with a mid-twentieth-century garage and a modern gazebo on the lot. The building matters for its Federal-era form and for its role in early county justice. Prominent New York attorneys argued cases here, and the 1802-1803 libel prosecution of printer Harry Croswell, brought over attacks on President Thomas Jefferson, began in this court. The exterior still reflects its original stately mass.","period_of_significance":"1786-ca.1850","architect_builder":"William H.
