The commission for the design of the Pennsylvania Capitol was awarded to Philadelphia architect Joseph M. Huston on February 25, 1902. Construction was completed four years later and the building was dedicated on October 4, 1906. Huston’s design of the interior incorporated an array of architectural styles, inspired by his travels through Europe. Typical interior finishes include: stenciled plaster walls, ornamental plaster crown moldings and ceilings (often gilded or glazed), marble wainscoting, mahogany paneling embellished with elaborate carvings, and terrazzo and Moravian tile floors.
