The Cloisters, also known as Cloisters Castle, is a historic home in Lutherville, Baltimore County, Maryland, United States. The building was completed in 1932, after three years of construction. The house is 4 story house, irregular in elevation and plan with much architectural ornament. It is built of large, random-sized blocks of a native gray and gold colored rock known as Butler stone, with details principally of sandstone, wood from the site, plaster, and wrought iron. The main façade is dominated by two asymmetrically placed, projecting sections topped by massive half-timbered gables which were originally part of a Medieval house in Domrémy, France. It also has a massive stone octagonal stair tower, which contains a stone and wrought-iron spiral staircase and is crowned by a crenellated parapet and a small, round, stone-roofed structure from which one can exit onto the roof of the main tower. The house's roof is constructed of overlapping flagstones secured by iron pins, the only roof of this kind in America. Read more on Wikipedia
