Pueblo Opera House

In June 1888 the architectural firm of Adler & Sullivan was contracted to design an opera house in Pueblo, Colorado.

[1] The exterior of the four-story building was designed in a combination Richardsonian Romanesque and Italian Renaissance style, with rusticated Manitou red sandstone on a granite base.

[2] The hall seated 1,200 people, and the balcony was the first in the United States to "span an auditorium without intermediate buttressing".

[3] The ceiling and walls of the auditorium were covered with Louis Sullivan's distinctive decorations.

On the night of February 28 – March 1, 1922, the Pueblo Grocers' Association's annual ball was held there, and it is believed that a cigarette may have ignited litter left behind after the event.
