The lower, or south-eastern, part contains both the small group of streets belonging to old Stuttgart, and also the most important part of the new town.
On the east and west the ravines already mentioned afforded, in the main, a sufficient protection, so that a massive wall was unnecessary, while near the south-eastern angle a breastwork was formed by the excavation of the natural rock, 2 which in later times was honeycombed with tombs.
Communication is thus most wanted with the northern and south-eastern extremities of the island, and between Tortoli and Nuoro, and Nuoro and Golfo degli Aranci.
The south-eastern portion of the city has been excavated only very partially.
Some Turkish colonies are also found in the south-eastern districts.
