Designed in the Mediterranean Revival style by architect Addison C. Mizner and completed by architect William E. Alysmeyer, Boca Raton Town Hall opened in April 1927 as the city's first municipal building, fire station, and police department. The Cramer & Cramer Construction Company developed architectural plans featuring an elaborate front entrance, a gilded dome atop the bell tower, and interior finishes with products of Mizner Industries. The Woman's Club opened Boca Raton's first public library here in 1927, and the second floor served for a number of years as the private residence of the fire chief. In its early years, the Council Chamber/Court Room was Boca Raton's only public meeting room and was used by numerous social groups as well as a polling place for city voters. In 1975 the city declared that the building should become a museum, and in 1976 the Boca Raton Historical Society located its office here. Recognizing its historic and architectural significance, Boca Raton Town Hall was listed in the National Register of Historic Places as "Old City Hall" in 1980. Several municipal offices occupied the building until 1983, and in 1984 the Boca Raton Historical Society restored Town Hall to its original architectural design for use as a local history museum and archives.
