6. The Keystone Building, 1923

A building with ornate decorations on the front of it.
The Keystone Building is one of two Stolp Island works by architect George Grant Elmslie. It is a relatively rare example of the Prairie School style used for an office building, and is listed individually on the National Register of Historic Places. Notice the subtle coloring of blue and gold in the organic terra cotta detailing. This type of decorative motif was originally developed by Louis Sullivan, Elmslie's former employer.
