The trapezoidal, stone-paved plaza that is now called Shockoe Slip opens southward from the corner of 13th Street. One side is defined by a wonderful Italianate commercial structure that curves around the corner. Now offices, it was originally built as a corn and flour exchange. The second and third visible floors of the exchange were constructed of brick but covered in stucco, which was scored to resemble stone. The window caps and cornice are cast iron, as are the risers of the interior staircase. The exchange room on the third floor retains its square cupola, market boards used to tally the prices of goods, and attenuated, cast iron Corinthian columns that punctuate the interior space. This was the first building on this part of East Cary Street to be renovated in the 1970s and is now used for stores and offices. The stone fountain in the plaza is a 1909 replacement of an earlier one used for watering horses.
