While I was in Charleston, Calli pointed out a series of cool maps to me. A park on the east side of the peninsula has a set of four sculptures representing the city of Charleston as it was in the 17th, 18th, 19th, and 20th centuries.
In the 17th century, the city takes up just the southernmost tip of the peninsula. Of course, it only had 20 out of those 100 years to grow.
The 18th century saw some growth north on the peninsula. I like the emerging pier on the Cooper River.
Charleston exploded in the 19th century, reaching the base of the peninsula. The docks on the Cooper River expanded as well.
Charleston in the 20th century saw two significant changes reflected in the map - the giant bridge over the Cooper River, and the elimination of several piers for the construction of Riverside Park.
I can't decide if the bridge is more impressive while you're driving over it after an overnight drive from Wisconsin, or looking at it cast in bronze or whatever.
