When I was an undergrad, I traveled around Europe. Italy was most surprising to me as the architecture was incredible, of course. This is when I fell in love with this cruel mistress. I have already posted some sketches from that time in the blog. This one is from a picture I took. Arcades played a central role in society in the old days, just as shopping malls do in this era. In fact, they are the predecessors of today’s shopping malls. It was very exciting to discover its steel and glass roof system then and is exciting to learn how to make it now.
