The turn of the 20th century marks a significant transition in the evolution of building architecture. The development of the steel skeleton enabled architects to reinvent the office building with previously unimaginable height. In addition to skyscrapers, the new century brought forth the Beaux Arts architectural style, which featured classical, yet beautifully proportioned and highly ornamented buildings, such as Cincinnati’s Memorial Hall, the Gwynne Building and Carnegie libraries. These programs are free and open to the public. A light meal is served at 5:45 pm for the first sixty attendees.
