Further modifications to the Town Hall continued to be made after its opening, beginning with the entrance steps being changed in part to semi-circular in the 1860s, Brodrick suggesting in 1867 that a larger skylight be put in each of the courts, and then, later in the same year, the placing of the four sculpted lions along the south front. Brodrick's final touches to the Town Hall, the lions are the work of William Day Keyworth Jr of Hull, and each is made from two pieces of Portland stone with zig-zag joints. Evidence of Brodrick's early interest in lion sculptures is documented in travel sketches from his European tour, at San Lorenzo Cathedral and the Palazzo dell'Università in Genoa, and the monument to Clement XIII in St Peter's, Rome.
