Hay Brown and William Heustis Keller, are cited as reasons for its significance.","narrative":"Built between 1852 and 1855 in Lancaster, Pennsylvania, the county courthouse was designed by Philadelphia architect Samuel Sloan in the Roman Revival style, chosen in the nineteenth century for government buildings to connect the Roman republic with the American republic. The main Duke Street front has pedimented pavilions with Cocalico sandstone Corinthian columns, and a copper-clad dome with four clock faces rises at the center of the roof. A north wing was added in 1896-98 by James H. Warner, who also designed Lancaster's Central Market, and C. Emlen Urban made revisions and added low wings on King Street in 1926-27. The building has served as the leading center of Lancaster County law and government since 1852. Attorneys Thaddeus Stevens, J. Hay Brown and William Heustis Keller practiced there, and the interior includes marble floors, mid-nineteenth-century wall paintings and a vestibule with two stairways leading to Courtroom Number 1.","period_of_significance":"1800-1899","architect_builder":"Samuel Sloan (architect); James H.
