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:Ogrodzieniec Castle is a ruined medieval castle originally built in the 14th–15th century by the W³odkowie Sulimczycy family. Established in the early 12th century, during the reign of Boles³aw III Wrymouth, the first stronghold was razed by the Tatars in 1241. In the mid-14th century a new gothic castle was built here to accommodate the Sulimczycy family. Surrounded by three high rocks, the castle was well integrated into the area. The defensive walls were built to close the circuit formed by the rocks, and a narrow opening between two of the rocks served as an entrance.
In 1470 the castle and lands were bought by the wealthy Cracovian townsmen, Ibram and Piotr Salomon. Then, Ogrodzieniec became the property of Jan Feliks Rzeszowski, the rector of Przemy¶l and the canon of Cracow. The owners of the castle about that time were also Jan and Andrzej Rzeszowskis, and later Pilecki and Che³miñski families. In 1523 the castle was bought by Jan Boner.
