The venerable stronghold of ACERENZA , northeast of Potenza, is not so easy to reach by public transport, although it does have a station on the FAL line to Gravina, in Puglia, a few kilometres below the town itself, connected by a regular bus service to the top. It's worth the effort for the grand panorama and its famous Cattedrale (daily 9.30am-12.30pm & 4-7pm), from which it is thought the name of Basilicata derives (it was the bishop of this basilica who exercised jurisdiction over the territory around). Constructed in the eleventh century but rebuilt in its present Romanesque form in 1281, probably by French Angevin architects, the cathedral has a time-worn exterior, though the cupola at the top is a recent addition, following the earthquake of 1930. Inside, its crypt is a rare example of the impact of the Renaissance in Basilicata.
