The Dorëzi Fortress is the oldest in the Tirana county and dates to the 9th century BC. The first archaeological expedition was performed in 1951. The ruins of the fortress are to be found in one of the highest hills of the Krrabë, at about 479 metres above sea level. It is thought that Dimale may have been situated in the Dorëzi Fortress.
The surrounding wall is in its southern part, and is 300 metres long from east to west. The fortress construction seems to have had three phases—the first with raw stones, the second with carved blocks placed with no mortar (Hellenistic period) and the third with crushed stones and the use of mortar (4th–6th centuries AD). One can see the main entrance of the fortress. The presence of old vases that date to those centuries suggests that the site was inhabited until at least the 4th–6th centuries AD.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.
