The Science and Industry Museum in Manchester is a large museum devoted to the development of science, technology and industry. It places particular emphasis on Manchester’s achievements and contributions in these fields.

The museum was originally called the North Western Museum of Science and Industry when it opened on Grosvenor Street in 1969 (SJ8497 : The North Western Museum of Science and Industry, Manchester). Having outgrown its former site, it was moved to its present location in Castlefield, where it opened on 15 September 1983. It later became known as The Museum of Science and Industry (MOSI) until its name was changed to the Science and Industry Museum in September 2018 to reflect it becoming part of the Science Museum Group.

The museum is housed in five listed buildings on the historic site of Liverpool Road Station which was vacated by British Rail in 1975. This station is the world’s oldest surviving passenger railway station; one of the original termini of the Liverpool and Manchester Railway, the world's first passenger railway.

The museum houses extensive displays on the themes of transport (railway locomotives and rolling stock, aircraft, and space vehicles), power (water, electricity, steam and gas engines), Manchester's sewerage and sanitation, textiles, communications and computing. There is currently no charge for entry to the museum.

Listed buildings and structures are officially designated as being of special architectural, historical or cultural significance. There are over half a million listed structures in the United Kingdom, covered by around 375,000 listings.
Listed status is more commonly associated with buildings or groups of buildings, however it can cover many other structures, including bridges, headstones, steps, ponds, monuments, walls, phone boxes, wrecks, parks, and heritage sites, and in more recent times a road crossing (Abbey Road) and graffiti art (Banksy 'Spy-booth') have been included.

In England and Wales there are three main listing designations;
Grade I (2.5%) - exceptional interest, sometimes considered to be internationally important.
Grade II* (5.5%) - particularly important buildings of more than special interest.
Grade II (92%) - nationally important and of special interest.

There are also locally listed structures (at the discretion of local authorities) using A, B and C designations.

In Scotland three classifications are also used but the criteria are different. There are around 47,500 Listed buildings.
Category A (8%)- generally equivalent to Grade I and II* in England and Wales
Category B (51%)- this appears generally to cover the ground of Grade II, recognising national importance.
Category C (41%)- buildings of local importance, probably with some overlap with English Grade II.

In Northern Ireland the criteria are similar to Scotland, but the classifications are:
Grade A (2.3%)
Grade B+ (4.7%)
Grade B (93%)
