The Old Surrogate's Building is an excellent Italianate structure with Renaissance detail. With City Hall, these two are described as the three most architecturally significant municipal buildings in Plattsburgh. The reviewer accepted the nomination under Criterion C.","narrative":"Two linked municipal buildings on Margaret Street in Plattsburgh make up this county government complex. The Clinton County Court House, designed by M.F. Cummings of Troy and built in 1889, is a massive Richardsonian Romanesque structure. A large square central tower with an open campanile and pyramidal roof rises above hipped roofs, rock-faced arches and belt courses. The first story is broken ashlar stone and the upper story is red pressed brick from Glens Falls. Beside it stands the Old Surrogate's Building, completed in January 1885 and attributed to Cummings. It originally housed the Surrogate, County Clerk and Board of Supervisors. This Italianate building has a bracketed cornice, molded stone lintels and Renaissance detailing. A modern Government Center and a court house annex, both non-contributing, adjoin the older buildings. Together with City Hall, the two historic buildings are considered the most architecturally significant municipal structures in the city, and the Court House still serves the county's legal system.","period_of_significance":null,"architect_builder":"Court House: architect M.F.
