Siena is the largest of the mountain towns in Tuscany. These mountain towns were built high on hills and are surrounded by tall walls. These fortifications came in handy when they found it necessary to dump hot oil on the invaders from neighboring towns fighting for dominance of the region and control of trade. I never thought I would be reading articles on the unification of Italy on my own and with interest…. The main attraction in Siena is the huge brick courtyard, Il Campo. Here the tradition is for young lovers to chase away the flocks of pigeons and have a picnic on the hot bricks… hummm we skipped that part.
