The Pythian Home of Missouri, also known as Pythian Castle, in Springfield, Missouri, was built in 1913 by the Knights of Pythias and later owned by the U.S. military. German and Italian prisoners-of-war were assigned here during World War II for medical treatment and as laborers. Some prisoners were kept in the detached powerhouse and laundry room behind the castle. The laundry room is still owned by the U.S. Army. The building was listed on the U.S. National Register of Historic Places on October 7, 2009. It is privately owned and open to the public for tours by appointment. Construction The main building was designed to give the structure the appearance of a castle which reflected the theme of the Knights of Pythias. Its foundation and exterior is constructed of "Carthage Stone", an especially hard variety of limestone commonly quarried in the Ozarks. The interior construction is composed of steel framework with poured concrete floors, ceilings, and stairways. The interior walls consist of layered hollow-core "Pyrobar Blocks" (a gypsum-based fireproofing material developed in the early 1900s), with a wire mesh covering that was coated with several layers of plaster. The original main floor features a grand foyer, meeting room, ballroom, dining hall, and sitting parlors. The second floor, which is accessed by dual staircases on either wall, was designed with dormitory style rooms for children and bedrooms for adults. The second floor also features a theater with original ticket booth, seats, upper projection and lighting room as well as changing rooms backstage. The building also features a full basement. The power house was located directly behind the main building and housed the boiler as well as the institution's laundry facilities.
