An arch is another design borrowed from the Romans. Arches were used in buildings thousands of years ago as well as on this building which was built about 100 years ago. Arches are even used in buildings today. Look at the structure just behind the Talmage Building. These are modern arches.
Columns are another ancient building element used on modern buildings.
Many modern buildings' form follows their function. That means the activities of the building were important to the way it was designed. No elaborate decorations adorn them. Even the functional building materials are exposed both inside and outside. Go inside the building and look at the building materials.
