The northern side of the city is uphill and is comprised of the residential area of town. The southern part, or port area (ports 1-4), is the commercial and tourist section that is comprised of shops, piers, and most of the restaurants. The city’s eastern side is protected by Fort San Cristobal. The western area of the city contains Paseo dela Princesa, La Fortaleza (Governor’s Mansion) and Fort El Morro. It is the oldest area of town where you can find 300-450 year old homes and buildings.
