The Old Capital exhibits the Greek Revival style while the four buildings that surround it display Beaux-Arts architecture.

The Pentacrest is a four-block park-like area including the zero-point of the street grid of Iowa City.

The axes are defined by Iowa Avenue and Capitol Street.

The decision was made that all buildings of the Pentacrest should be the same color; therefore, Calvin Hall was moved intact across Jefferson Street and Macbride Hall was built in its place.
