  Bordered by Corso Castelfidardo, Corso Vittorio Emanuele II, Corso Trapani and Corso Peschiera, this small district is mainly significant for hosting the recent expansion of Turinese institute of technology Politecnico. The expansion was possible after under-grounding the railway under Corso Castelfidardo and the subsequent disposal of the old buildings dedicated to the train maintenance present in this area (so-called Officine Grandi Riparazioni or OGR). Politecnico expanded its facilities through two huge overpass buildings over the avenue, linked to new buildings on the west side. This cluster of buildings forms an evocative square with a unique architectural style. The main building on the west side hosts a General Motors research centre, the General Motors Global Propulsion Systems (formerly known as General Motors Powertrain Europe). Politecnico area extends until Via Boggio with further facilities hosted in the former OGR facilities. The institute plans to further build new facilities in the current parking area.
  
  North of Politecnico facilities, the main building of the OGR former cluster, which consists in three 180-meters long joint parallel buildings, became recently a big open space which hosts temporary exhibitions and during the hot seasons, its external spaces became a fashionable site to have a typical Italian aperitivo.
  
  North of OGR, a former prison complex called Le Nuove is a significant example of old European prison building. The complex was built between 1857 and 1869 during the reign of Victor Emmanuel II. After being disposed of during the 1990s, the complex was changed into a museum and it is possible to visit its facilities.
  
  An example of contemporary art is the heating plant in Corso Ferrucci, which has been covered with aluminium panels. Another building (19th century), now abandoned, is the former Westinghouse factory of train brakes situated in Via Borsellino.
  
  The residential and business zone of the district sprawls westward, beyond the former—now demolished—customs wall (cinta daziaria), which previously separated the city from the mainly rural landscape that marked the outskirts of Turin until the late 19th century. Urban planning outside the local city gate (so-called barriera di San Paolo) led to the construction of an industrial and working-class neighborhood in the early 20th century, although factories have long been discontinued, torn down or converted to other uses nowadays. Together with San Paolo district, Cenisia hosts an extensive street market along Corso Racconigi, which is locally known as the longest street market in Europe.
