Salzburg's "Old Town" (Altstadt) is internationally renowned for its baroque architecture and is one of the best-preserved city centers north of the Alps. It was listed as a UNESCO World Heritage Site in 1997. The city has three universities and a large population of students. Tourists also frequent the city to tour the city's historic center and the scenic Alpine surroundings.
Traces of human settlements have been found in the area, dating to the Neolithic Age. The first settlements in Salzburg continuous with the present were apparently by the Celts around the 5th century BC.
Around 15BC the separate settlements were merged into one city by the Roman Empire. At this time, the city was called "Juvavum" and was awarded the status of a Roman municipium in 45 AD. Juvavum developed into an important town of the Roman province of Noricum. After the collapse of the Norican frontier, Juvavum declined so sharply that by the late 7th century it nearly became a ruin.
An adit (from Latin aditus, entrance) is an entrance to an underground mine which is horizontal or nearly horizontal, by which the mine can be entered, drained of water, ventilated, and minerals extracted at the lowest convenient level. Adits are also used to explore for mineral veins.
Adits are driven into the side of a hill or mountain, and are often used when an ore body is located inside the mountain but above the adjacent valley floor or coastal plain. In cases where the mineral vein outcrops at the surface, the adit may follow the lode or vein until it is worked out, in this case the adit is rarely straight. The use of adits for the extraction of ore is generally called drift mining.
Adits can only be driven into a mine where the local topography permits. There will be no opportunity to drive an adit to a mine situated on a large flat plain, for instance. Also if the ground is weak, the cost of shoring up a long adit may outweigh its possible advantages.
The 491 Gallery was a squattedsocial centre and multi-disciplinary gallery in Leytonstone, London, England, that operated from 2001 to 2013. Taking its name from its street number, 491 Grove Green Road, the former factory was home to a community-led art organisation and served as an exhibition space for a diverse range of artists of different origins working in varied media. It contained a range of art and music studios, which were used to host workshops, classes and musical rehearsals.
The building, originally a factory, was later used as a storage space and warehouse for materials being used to construct the A12 that cuts through Leytonstone and the surrounding areas. Unlike the rest of the surrounding buildings, it and the few neighbouring houses were not subject to compulsory purchase orders and demolition for the A12 site. When in late 2000 the building was abandoned, it became occupied by a group of homeless drug users, who remained in it for some six months. Within a month of their vacating the premises, the building was reoccupied by a group of artists, who spent the next several years turning it into a community space. The neighbouring building, formerly houses, was also occupied, and named Vertigo, after the film by Alfred Hitchcock, a famous resident of Leytonstone.
