Colonial Theatre, also known as the Lochiel Hotel, is a historic theater and commercial building located at Harrisburg, Dauphin County, Pennsylvania. The building consists of a five-story, brick and frame front section and a rear brick and frame auditorium. The original Colonial Theatre was built about 1836, as a hotel in the Greek Revival style and featured a four columned portico on the Market Street entrance. It was subsequently modified in form and use a number of times. In the 1870s, a mansard roof was added.
The rear auditorium was added in 1912, when the building was converted from a hotel to hotel and movie / vaudeville theater. The lobby was remodeled in the 1930s / 1940s in an Art Deco style; the auditorium has Italian Renaissance style detailing. The theater and hotel closed in 1976, and the building used for offices and shops.
