Fodor's Expert Review Castello di San Giusto

This hilltop castle, built between 1470 and 1630, was constructed on the ruins of the Roman town of Tergeste. Given the excellent view, it's no surprise that 15th-century Venetians turned the castle into a shipping observation point; the structure was further enlarged by Trieste's subsequent rulers, the Habsburgs. The castle also contains the Civic Museum, which has a collection of furnishings, tapestries, and weaponry, as well as Roman artifacts in the atmospheric Lapidario Tergestino.
