Fodor's Expert Review Castello

Perched over the vast expanse of Cagliari and its port, this hillside quarter has narrow streets that hold ancient monuments and piazzas amid apartments with wash hung out to dry on elaborate wrought-iron balconies. The most impressive entrance is through the commanding late-19th-century archway of the Bastione di St. Remy on Piazza Costituzione. Entering this way means climbing numerous steps; if this is a problem, walk up Viale Regina Elena to find an elevator. At the top is an impressive panorama of the cityscape and the Gulf of Cagliari. From Piazza Palazzo, holding Cagliari's cathedral, you can walk to Piazza Indipendenza and the Museo Archeologico.
