The Boulevard Saint-Michel is one of the two major streets in the Latin Quarter of Paris (the other being the Boulevard Saint-Germain). It is a tree-lined boulevard which runs south from the pont Saint-Michel on the Seine river and the Place Saint-Michel, crosses the boulevard Saint-Germain and continues alongside the Sorbonne and the Luxembourg gardens, ending at the Place Camille Jullian just before the Port-Royal railway station and the avenue de l'Observatoire. It was created by Baron Haussmann to run parallel to the rue Saint-Jacques which marks the historical north-south axis of Paris.
The man walking to the left of us later fell over flat on his face the poor thing! No damage though - just a sore nose.
