The stairwells and their domes or rotundas have been restored to
their original paint colors. The floor plan is laid out with a dome-covered
stairwell at each building corner and a rotunda-covered double stairwell.
There are a total of eight monumental circular stairwells in the building.
The four corner monumental stairs extend from the ground floor to the
fourth floor. The two pair of monumental stairs on the east and west ends
of the center hallway extend from the ground floor to the fifth floor.
The stairs are made of solid granite slabs that are set into the wall and
then extend out over the stairwell below. The mahogany railing is supported
by over 4,000 solid bronze balusters.
The stairs and hallways have been restored to their original
state. Here is one of the two matching south stairwells.
