SK5739 : 53 Castle Gate, Nottingham
taken 6 years ago, near to Nottingham, England

These premises constitute the whole of the south side of Castle Gate between Maid Marian Way and Castle Road.
They represent a range of town houses dating from the 17th to the 19th centuries. At various dates they were converted to business use, part of the range housing the City Architect's offices between the 1960s and 1974, when the costume and lace museums were installed. These moved out in 2004 and the buildings appear to have been largely unoccupied following that date. They were sold to a developer in 2013 and have now been re-converted to residential use as individual houses. No.55 and 57 have been combined, with no.59, originally a pair to 57, has been linked to Severns House as office accommodation.
All buildings are Listed Grade II.
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%)
