The Santa Justa Lift is an elevator, or lift, in the civil parish of Santa Justa, in the historical city of Lisbon. Situated at the end of Rua de Santa Justa, it connects the lower streets of the Baixa with the higher Largo do Carmo (Carmo Square).
Since its construction, the Lift has become a tourist attraction for Lisbon as, among the urban lifts in the city, Santa Justa is the only remaining vertical (conventional) one. Others, including Elevador da Glória and Elevador da Bica, are actually funicular railways, and the other lift constructed around the same time, the Elevator of São Julião, has since been demolished.
The hills of Lisbon have always presented a problem for travel between the lower streets of the main Baixa and the higher Largo do Carmo. In order to facilitate the movement between the two, the civil and military engineer Roberto Arménio presented a project to the Lisbon municipal council in 1874.
In 1900, the formal contract was signed on which the working group was obligated to present a project for an elevator in a period of six months. On 31 August 1901, King Carlos inaugurates the metal bridge and awning. Yet, its operation would wait until 1902. Originally powered by steam, it was converted to electrical operation in 1907. After remodelling and renovation, on February 2006, the Elevator walkway was reopened for the general public and tourists.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.
