Wandering the streets of Cagliari's old city can be claustrophobic. The multi-story buildings are crammed in together and tilting every which way, often giving a zig zag effect that mirrors the maze-like streets. But emerge from the darkness (and above the tourist shops) for a breath of fresh air at the Piazzetta David Herbert Lawrence. There are a few restaurants along the piazzette, but the real draw is the view. It's centrally located, giving you a resplendent panoramic of the city.
