Numana sits on a cliff a few kilometres south of Sirolo, divided into the upper town (Numana Alta) and a lower harbour district (Numana Bassa). The upper town is the prettier half: a small grid of streets, the Arco di Torre — a medieval arch that is all that remains of an older fortified gate — and an excellent regional Antiquarium with finds from the Picene tombs of the surrounding area.
The lower town is built around a small fishing port that is also where the boats for the cliff beaches leave from. Numana works well as an alternative base to Sirolo, slightly cheaper and slightly more workaday.
