Spacious enough to make cave-dwelling seem like a viable accommodation option, this large domed cavern, high on a cliff above the harbour, has been continuously occupied since the last ice age – about 18,000 years. It's open to the sky, so even the most claustrophobic shouldn't baulk at visiting. There's not actually an awful lot to see here, but information panels (in English and Croatian) explain the ongoing archaeological work taking place.
It's signposted from town but the signs are a little hard to spot.
