The 240,000-square-foot Clay Center for the Arts and Sciences of West Virginia is located at One Clay Square in Charleston, West Virginia. One of the few centers of its kind in the U.S., it aims at enhancing the region's "quality of life" and enriching “the lives of all West Virginians." Having opened its doors to public in July 2003, the center has become one of the state’s leading interactive cultural destinations. It presents the performing arts, visual arts, and the sciences under one roof. Occupying a whole city block in Charleston, the Clay Center has a black box theater, a visual arts museum, a hands-on science museum specially designed for kids, and a planetarium. The Maier Foundation Performance Hall located here, is a 1,883-seat theater with exceptional acoustics and sight lines. The Walker Theater is the Center’s black-box theater, which can accommodate between 150 and 200 people, depending on the configuration. The Avampato Discovery Museum features an art gallery and a theater - the Electric Sky Theater. The gallery displays selections from the museum's permanent collections and traveling exhibitions. The theater presents planetarium shows and large format films on its giant domed screen. In addition to the West Virginia Symphony Orchestra, the Clay Center sponsors a world-class performance series. There is also a cafe, the Douglas V. Reynolds Intermezzo Cafe; and a gift shop, the BB&T Little Shop of Wonders Gift Shop. The shop sells items from West Virginia and out-of-state artisans.
