Doing today's drawing assignment in a covered, and heated, arcade was a welcome change in pace. Rome's unusually cold winter has been brutal in the past few weeks but today we did our architecture work indoors. We studied the layout and proportions of the Galleria Colonna on Rome's main commercial boulevard, Via Del Corso. The gallery was built in 1914 and is the oldest arcade in Rome. The arcade of Galleria Colonna was modeled after another arcade in Milan, although even earlier versions existed in Paris and London. Today this gallery, and other early twentieth century arcades, functions as a shopping mall and hosts many high end designers.
