Why go

Tuvixeddu explains Punic Cagliari, while the archaeological museum connects the capital with the rest of the island. In Cagliari, this sights context changes how Cagliari's principal landmarks and its surrounding landscape fit together.
The full story
Start in Castello with the cathedral, the Pisan towers and the Bastione di Saint Remy, then descend through narrow lanes toward Marina. Tuvixeddu explains Punic Cagliari, while the archaeological museum connects the capital with the rest of the island. Poetto and Molentargius are better treated as a separate coastal circuit. These places make sense as a sequence, not a checklist. Begin with the anchor that explains Cagliari's development, then use the surrounding streets or landscape to connect later periods. Check access to interiors on the day, since churches, archaeological areas and small museums can close independently even when the town itself remains easy to explore. Keep the comparison grounded in Cagliari: notice how materials, routes and the surrounding terrain shape what survives. That approach preserves the useful legacy context without turning a visit into a list of names or dates.
