First World War, dedicated by the classes of 1918 and 1919. There was an addition to Lincoln Hall in 1929. The renovation cost $500,000 and extended the building west to Wright Street and added a theater. Also, in 1950 Lincoln Hall became the first building on campus with wheel-chair assessable ramps. In 2005, the Landmarks Preservation Council of Illinois placed Lincoln Hall on its yearly Ten Most Endangered list. In July 2009, Governor Pat Quinn approved $60.3 million for the renovation of Lincoln Hall. The University of Illinois pledged to pay $6 million for the renovation. The plan brought the building up to the contemporary building code. The renovated building was ready for occupancy in July 2012. The entire exterior of the building was restored including the slate of roof tiles, windows, brick mortar, detailing, and the 30 terra cotta panels depicting quotes and portraits from Abraham Lincoln's life. On the Wright Street side of the building, the old carriage porch was restored into the formal entrance for the building. As for the interior of Lincoln Hall, the theater, east foyer, and some detailing were restored. The Lincoln Hall Theater was returned to its original look by using historical colors and preserving the decorative iron ends of seats, the tablets, and frescoes. A new stage curtain, seats, stage equipment, projectors, and a control room were added. The refinishing of the interior of Lincoln Hall included 5,000 feet of original white oak paneling, baseboard, door cast, and trim. In the entrance foyer from the Quad, the barrel vault ceiling, Gettysburg Address tablet, marble floors, and pillars were restored. The bust of Lincoln still overlooks the foyer. Since the renovation of Lincoln Hall, air conditioning and wireless connection are installed throughout the entire building. All 18 classrooms are on the first floor and each classroom has audio/visual capacity. Every classroom is equipped with projectors, display screens, chalkboards, and speakers. Office suites are on the upper floors and include conference rooms equipped for presentations and meetings with faculty. The renovation of Lincoln Hall is also eco-friendly. The roofs within the courtyards are covered with plants reducing rain runoff and increasing the lifespan of the roof. The slate roofing tiles were recycled as mulch for the grounds. Storm drains and sanitary sewers are relined instead of replaced eliminating the need for excavations and new pipe. New building materials—at least 20 percent of which is
