His largest single commission was a programme of architectural sculptures for the Manchester Assize Courts, built in Manchester from 1859 through 1864. Woolner created a large number of statues depicting lawgivers and rulers which formed part of the building's structure. Most dramatic was a giant sculpture depicting Moses which was placed on the top, above the entrance. There were also allegorical figures of "Justice" and "Mercy". Inside was a relief sculpture depicting the "Judgment of Solomon", flanked by statues of a "Drunk Woman" and a "Good Woman". Alfred Waterhouse, the architect, wrote, "we are all delighted with your virtuous woman, and disgusted as we ought to be with the awful example." The building was bombed during World War II. Some of the sculptures were saved and incorporated into the replacement building.
