The Archaeological Park of Lipari is located at the Diana district. In the park there are the remains of walls for a length of about 50 m, a tower of the 4th century BCE and some Roman fortifications built by Sextus Pompey.
Behind the Greek walls there are buildings of the Imperial-Roman period (2nd century AD). Within the walls there is a street with some home facades of the Imperial-Roman period, mainly located under the modern town and the traces of the town destroyed by the eruption of the 8th century BC. Beyond the walls there was the necropolis and few remains have been discovered. Near the northern entrance of the Park and the Archbishop’s Palace there are the remains of funerary monuments of the late Roman Imperial period and tombs of the 1st century BC.
In the same area there are walls built during the late Roman Imperial period which goe beyond the Via della Conciliazione, partially detached from the Park. San Calogero are the oldest thermal baths of the ancient world and they date back to the final stage of the Culture of Capo Graziano (between the end of the 16th and the beginning of the 15th century).References:
The Broch of Gurness is an Iron Age broch village. Settlement here began sometime between 500 and 200 BC. At the centre of the settlement is a stone tower or broch, which once probably reached a height of around 10 metres. Its interior is divided into sections by upright slabs. The tower features two skins of drystone walls, with stone-floored galleries in between. These are accessed by steps. Stone ledges suggest that there was once an upper storey with a timber floor. The roof would have been thatched, surrounded by a wall walk linked by stairs to the ground floor. The broch features two hearths and a subterranean stone cistern with steps leading down into it. It is thought to have some religious significance, relating to an Iron Age cult of the underground.
The remains of the central tower are up to 3.6 metres high, and the stone walls are up to 4.1 metres thick.
