The only window in an ancient Italian home

I don't even know the name of the town. I do remember it was in Northern Italy above Milan and close to the border with Switzerland. Near the very old town's round village fountain and down a narrow alley, there in the middle of a block-length 2 story high wall was this single tiny window. Across the window, set into the foot deep walls, was a handmade twisted iron bar. Tied to the bar with string was this pot and it's three lovely geraniums.
