The Minnesota State Capitol architect, Cass Gilbert, was a perfectionist with stunning results for his home town of Saint Paul. The rotunda walls are veneered limestone from Kosota, Minnesota. The columns are Minnesota bronze granite and their capitals (top of columns) are a Lady Slipper motif, the state flower. The band of red stone is also local. Gilbert decorated the three floors of the rotunda with circles: a glass one in the floor, a circle of arches, a ring of balusters, ornamental ironwork that is round and a globe chandelier. The surrounding murals are called Civilization of the Northwest by Edward Simmons.
