English: Mozart Hall, 340 Main Street, Latrobe, Pennsylvania, June 2021. One of the most architecturally unusual and significant buildings in the city, Mozart Hall was erected in 1890 by George Seiler and boasts a dazzling - and dazzlingly restored - Art Nouveau decorative scheme which, along with its name, honors Seiler's family roots in Salzburg, Austria and the building's original function as a dance hall and opera house. Witness especially the twin onion domes that bookend the front gable facing Main Street, adorned - as with the rest of the façade, by ornate relief carvings in the form of leaves, vines, and flowers. Along with Columbus Hall on Ligonier Street, Mozart Hall is also one of only two remaining buildings in Latrobe with cast iron façades. The dance hall was located on the second floor, with an interior characterized by a pressed-metal ceiling, stage, and balcony, and was used for musicals and operettas until the Showalter Opera House (demolished) opened on Depot Street. The commercial storefronts on the ground floor remain occupied, but the rest of the building is vacant and the subject of ongoing reuse proposals.
