The Wisconsin Club’s City Club was originally the residence of industrialist Alexander Mitchell and his wife Martha, grandparents of World War I hero, General Billy Mitchell. They built the original home in 1848.
In 1859 it was remodeled in the fashionable Italianate style. In 1871, an Italian woodcarver was hired to build the Belvedere (an enclosed Gazebo) on the southeast corner of the grounds. In 1872 wings were added to both sides of the mansion, the porch enlarged and bay windows installed.
In 1876 Alexander Mitchell commissioned noted architect Edward Townsend Mix to transform their home into the French Second Empire mansion it is today. Artists from Europe adorned the interior with elaborate hand-carved mahogany woodwork, stained glass, plaster and inlaid tile. The hand-carved Grand Staircase in the East Hall is adorned with twenty-four lion heads. In the South Lounge, there are over sixteen hundred hand-carved pansies on the ceiling.
The Wisconsin Club (formerly the Deutscher Club), purchased the mansion in 1898. As the Club’s membership has grown and the mansion has gone through numerous renovations and remodeling projects over the many years, attention to the mansion's heritage and architectural beauty have remained intact. Each year, the Club budgets the necessary resources to maintain the one-of-a-kind architectural treasure. The Clubhouse is ADA compliant. It has updated HVAC and AV systems, and has Wi-Fi.
