Hop on bus 19 from Piazza XXIV Maggio to visit Salerno’s most famous landmark, the forbidding Castello di Arechi, dramatically positioned 263m above the city. Originally a Byzantine fort, it was built by the Lombard duke of Benevento, Arechi II, in the 8th century and subsequently modified by the Normans and Aragonese, most recently in the 16th century.

The views of the Gulf of Salerno and the city rooftops are spectacular; you can also visit a permanent collection of ceramics, arms and coins. If you are here during summer, ask the tourist office for a schedule of the annual series of concerts staged here.
