Local legend says that Wm Jennings Bryan spoke at the hall during the 1896 presidential campaign. Others who have been to the hall include Theodore Roosevelt, John Phillips Sousa, Marx Brothers. Decline began with the advent of the movies, for which it was converted. By the time of World War II it was an abandoned building. Beginning in 1955, the Community Theatre Guild leased the property and began maintaining it once again for theater productions.:47 The City restored the hall in the 1990s and leased it to the Memorial Opera House Company, where theater productions continue.
The Memorial Opera House is located at 104 Indiana Avenue just east of the historic Porter County Jail and Sheriff's House. At the time of construction, Indiana Avenue was called Mechanics Street. The Opera House was added to the National Register of Historic Places in 1984. It was restored in 1998.Today, the Memorial Theatre Company produces six theatrical performances each year and host community concerts and other events. p:74–75
The 1893 Memorial Opera House is "eclectic" in its styling, with the details, symmetry, and size associated with the Queen Anne style. Additional influences are seen in the broad entrance arches and side windows. This may reflect the influence of Louis Sullivan or H. H. Richardson, both active in nearby Chicago during this time.
The main facade features a projecting, two-story central bay, with a jerkin-head gable. The ground floor of the bay is occupied by a broad, low-springing arch, formed by seven header courses of brick with rock-face limestone springers. The main entrance consists of two pairs of multi-light doors. Eight radiating lights fill the tympanum. Above the entrance is a recessed panel on a stone sill with the inscription, "1883, Memorial Hall, A monument to the Soldiers and Sailors of 1861-5." Above the dedication stone is a limestone sill and a fanlight with clear and stained glass set in a seven-course brick arch. A coved verge board outlines the edge of the jerkin-head gable, and is decorated by rosettes. On both sides of the central bay there are a single bay. At ground level, the windows are segmentally arched double-hung, with stone sills level with the springers of the central arch. Above, the double-hung windows have stone sills, and a stone belt course, serving as the lintels. A parapet with rounded "shoulders," on a stone cornice of corbelled brick. Two round towers frame the main facade. Rectangular windows have a stringcourse forming the sills, in line-with the central arch springers. A rock-faced belt course forming the lintels. Decorative brick detailing above the windows forms a foundation for a floriated frieze, with a modillioned cornice. Two-story structure has a pitched roof, interrupted by hipped roofs over projecting bays. Round-arched windows on each side, replicate the main façade. Shallow buttresses, interrupt the wall surface
The interior retains the orchestra pit and side boxes. The boxes are framed by turned posts, and the appliqué decorated railings. Latticework, similar to that used in Queen Anne houses, connects the posts across the top. A new floor with modern seating was installed in 1967, along with improvements to the orchestra pit. The improvement cost about $250,000.
Live performances were the mainstay at the Opera House until the 1920's. Then, movies began to compete with and soon replace live performances. Some films and performances by local groups shared the stage during the 1920's, 30's and 40's. The Opera House was vacant as much as it was in use. In the 1950's demolition was being considered. In 1957 the Community Theatre Guild was formed with the express purpose the renovation and preservation of the Opera House. The Guild arranged a lease from the County Commissioners, and began making repairs and creating a stage for local talent. Work peaked in 1967, when a $250,000 renovation project was undertaken. The Guild continues to operate and upgrade the Opera House. The building itself skillfully combines elements typical of the 1890's into a gracious composition most easily described as Queen Anne. The building has remained remarkably intact, providing an excellent example of this type of facility from the Victorian era.
