It opened in 1906 as part of the original Interborough Rapid Transit (IRT) system and lies 121 feet below the street in the Fort George Tunnel.","why_significant":"The station is significant for its role in opening northern Manhattan to development and for its engineering, as one of the deepest stations in a rock tunnel that was among the longest in the U.S. when opened. It is also significant as a classic Beaux-Arts station by architects Heins & LaFarge, with elaborate tile, terra cotta and mosaic ornament. It is the only station where the concrete barrel-vaulted ceiling is exposed to view.","narrative":"Buried 121 feet beneath St. Nicholas Avenue in Washington Heights, this subway station opened in 1906 as part of the first Interborough Rapid Transit line. It sits inside the Fort George Tunnel, a two-track rock tunnel that was the second longest in the country when it opened. Engineer William Barclay Parsons handled the structure, while architects George L. Heins and Christopher G. LaFarge designed a Beaux-Arts interior with white ceramic tile, marble, terra cotta rosettes, mosaic friezes and name tablets, including some reading George Washington Bridge. Its exposed concrete barrel-vaulted ceiling is unique in the system. Platforms were extended in 1909 and 1948, and a second elevator tower was added in 1909. Over time, advertising panels, closed crossings and missing mosaics have affected the interior, yet it keeps a high degree of integrity. The line also helped open upper Manhattan to apartment development and reinforced 181st Street as a major crossroads.","period_of_significance":"1906-1948","architect_builder":"William Barclay Parsons (engineer); George L.
