Manhattan in Chicago?

The Manhattan Bldg (1889) was the first all metal skeleton framed building, and when completed, it was also for a brief time, the tallest office building at 16 story's. (The tower on the Auditorium Bldg was taller.)

The original plans called for a steel frame, but the price of steel was considered too high. Instead they used cast iron and wrought iron, both of which have a much lower melting point in a fire.

It's interesting how out of alignment the bay's have gotten in the last 115 years.
