Pietra di Vobbia Castle is a rare example of contamination between the work of men and nature, the Castle of Pietra overlooks the Scrivia Valley. An unconquerable fortress, it is built between two rock towers. Recently restored, you can visit it today in all its ancient charm.
Embedded between two rock towers and perfectly integrated with nature, the castle of Pietra di Vobbia has retained the typical atmosphere of the impregnable medieval fortresses, a symbol of the feudal power of its rulers.The castle was built around the year 1000 to preside over the road connecting Vobbia to Canton Island, Via del Sale (Salt Road) to Postumia road.
Its name originates from Opizzone della Pietra, a family in charge of the feud. You can see only a part of it from the valley, and this already tells a lot about how difficult it was to seize it. Like in 1200, when the Republic of Genoa itself had to step in to rescue two men held captive by the Opizzone family. From here, in fact you can control the roads of four provinces (Genoa, Alessandria, Pavia and Piacenza) and, thanks to a clever reference system, a message could quickly be sent from the port of Genoa to Tortona.Its peculiar location made its restoration a complicated affair too; started in 1970, restoration work has now been completed and everyone can visit it.References:
Roman Walls of Lugo are an exceptional architectural, archaeological and constructive legacy of Roman engineering, dating from the 3rd and 4th centuries AD. The Walls are built of internal and external stone facings of slate with some granite, with a core filling of a conglomerate of slate slabs and worked stone pieces from Roman buildings, interlocked with lime mortar.
Their total length of 2117 m in the shape of an oblong rectangle occupies an area of 1.68 ha. Their height varies between 8 and 10 m, with a width of 4.2 m, reaching 7 m in some specific points. The walls still contain 85 external towers, 10 gates (five of which are original and five that were opened in modern times), four staircases and two ramps providing access to the walkway along the top of the walls, one of which is internal and the other external. Each tower contained access stairs leading from the intervallum to the wall walk of town wall, of which a total of 21 have been discovered to date.
The defences of Lugo are the most complete and best preserved example of Roman military architecture in the Western Roman Empire.
Despite the renovation work carried out, the walls conserve their original layout and the construction features associated with their defensive purpose, with walls, battlements, towers, fortifications, both modern and original gates and stairways, and a moat.
Since they were built, the walls have defined the layout and growth of the city, which was declared a Historical-Artistic Ensemble in 1973, forming a part of it and becoming an emblematic structure that can be freely accessed to walk along. The local inhabitants and visitors alike have used them as an area for enjoyment and as a part of urban life for centuries.
The fortifications were added to UNESCO"s World Heritage List in late 2000 and are a popular tourist attraction.
