From the website:
One hundred years ago, Bascom Hall underwent a momentous change. The imposing dome that once topped the building burned on Oct. 10, 1916. Fortunately, the rest of the structure was spared and Bascom has survived looking pretty much the same for the century since. But go back further and you'll see some striking differences. This gallery of Bascom Hall images reveals how much the iconic landmark has evolved over the years before, during and after the fire.
