Following a design contest in 1891, the plans of architect Henry C. Koch and Company were chosen for the new city hall. Henry Koch designed a plan for a nine-story building with a Flemish-Renaissance style, a style that reflected the tastes of much of the German population in Milwaukee. Builders laid the first cornerstone on February 24, 1894, and City Hall officially opened its doors with dedication ceremonies on December 23, 1895. The total cost of the construction was $945,311.
There is 107,270 square feet of office space within City Hall, with an open well, 20 ft. x 70 ft., in the middle of the 320-foot building (including the bell tower). A flagpole stands on top of the building at a total of 393 feet above the ground.The bell in the tower is named Solomon Juneau in honor of the very first elected mayor of Milwaukee. The clock face is 18 feet across, and it was believed to be the third largest in the world at the time of its completion.
Since its original construction, City Hall has gone through several restoration projects and wind, rain, and age have worked their powers on the building. The most recent significant project ran from 2005-2008. Today visitors can explore the building on a tour and see firsthand the results of the restoration efforts.
