High Quality Content by WIKIPEDIA articles! The Warner Theatre is an Art Deco and French Renaissance-styled theater located in downtown Erie, Pennsylvania in the United States. It was listed on the National Register of Historic Places in 1982. The Warner was designed by Chicago-architects Rapp and Rapp and was opened in 1931. It was used as a movie theater until 1976, when it was sold to the City of Erie. In the early 1980s, Erie converted the theater to a performing arts center, which has become the focus of a downtown revival.
