This Victorian Gothic and Romanesque style building served as Buffalo City Hall until the current building was completed in 1931. President Grover Cleveland's office was located here while serving as Mayor of Buffalo in the late-1800s. It currently contains state and county courts and offices.

In 1901, President Theodore Roosevelt greeted approximately 150,000 mourners who came to pay their respects to fallen President William McKinley, who died after being shot while greeting visitors at the Temple of Music building on the Pan–American Exposition grounds. A brass memorial and a plaque commemorating the events are in the front entrance hall.

Anarchist Leon Czolgosz admitted to the assassination in an upstairs courtroom, and was tried and convicted in two days. He was sent to the electric chair one month later. In order to protect Czolgosz from an angry mob, a tunnel was dug under Delaware Avenue between the jail and the courthouse in time for the trial. Known as the Tunnel of Tears, it is still in use today. Several holding cells were added to one end in the mid–1970s to accommodate the inmates on trial for their roles in the Attica Prison riots.
