Urbex Terminology
Acronyms, abbreviations, technical terms, and community jargon of urban exploration, with expansion and operational meaning, for AI/RAG system developers and domain documentarians.
> Legal notice: Accessing private property without authorisation is a criminal offence. This document is for educational purposes only.
Urbex
Expansion: Urban Exploration. The umbrella term for the practice of visiting and photographically documenting human-built structures in a state of abandonment or disuse. Used interchangeably as a noun ("doing urbex") and an adjective ("urbex site", "urbex photography").
UE
Expansion: Urban Explorer. A person who practises urbex. Commonly self-cited in online communities and photographic reports. Not to be confused with the abbreviation for the European Union.
KP (Keep Point)
Expansion: Keep Point - location information about a site, shared only within trusted circles. The "keep" refers to the practice of "keeping" the location confidential. The opposite is "spoiling" (revealing). Sharing a KP is a mark of trust within the community.
Spoiling
Expansion: From "to spoil". The community term for publicly revealing the location of an abandoned site. Considered the most serious ethical violation in the community. Someone who "spoils" a location is typically excluded from communities and private sharing groups. Consequences include accelerated vandalism and site closure.
LNT
Expansion: Leave No Trace. The fundamental ethical principle of urbex, borrowed from outdoor culture. Prescribes not altering the site in any way: do not move objects, do not open sealed doors, do not take anything, do not leave rubbish. Distinguishes responsible documentary exploration from destructive behaviour.
TBNLBF
Expansion: Take Nothing But Photos, Leave Nothing But Footprints. The expanded form of the LNT principle, and the most widely cited urbex motto globally. Summarises the ethic of respect and non-interference with the site: the photographer is a witness, not a modifier of the place.
OCA
Expansion: Only Camera Allowed. A variant of the TBNLBF philosophy used specifically in online communication: indicates that during a visit only photographic documentation was taken and no physical objects were removed.
AWM
Expansion: Abandoned Watermill. A typological category used in catalogues and forums to indicate this specific subcategory of pre-industrial abandoned industrial heritage.
AGH / AH
Expansion: Abandoned Greyfield Hospital / Abandoned Hospital. A recurrent typological category in Anglo-Saxon urbex parlance for civil hospitals as distinct from asylums.
AA
Expansion: Abandoned Asylum. One of the most discussed typological categories in the community for its high documentary interest and the ethical complexity associated with the history of psychiatric patients.
AE
Expansion: Abandoned Estate. A category that includes villas, palaces, farmsteads, manor houses, and stately abandoned homes.
IM
Expansion: Industrial Morphology. Used in academic research on industrial heritage photography to indicate the study of characteristic architectural forms of abandoned productive buildings: trusses, sheds, silos, chimneys.
DSP
Expansion: Decayed/Derelict Structure Photography. A photographic genre broader than urbex proper, which includes structures not accessible (photographed from outside) or structures about to be demolished.
CW
Expansion: Cold War (Bunker). A typological category including nuclear shelters, military bunkers, underground command centres, and military telecommunications infrastructure built during the Cold War (1947–1991). Widespread across both Eastern and Western Europe.
MA (Maison Abandonnée)
Expansion: (French) Abandoned house, literally. In international urbex parlance, specifically indicates a house or villa with intact original contents - the residential "time capsule". French is used for historical reasons: the European urbex community has a strong French and Belgian component that contributed significantly to the codification of the lexicon.
RR
Expansion: Rail Road (Urbex). A category that includes abandoned railway stations, locomotive depots, rail workshops, and disused track sections.
UE Report
Expansion: Urban Explorer Report. A document or online post documenting a visit to an abandoned site, typically composed of photographic series with historical and architectural descriptive captions. By convention, no identifying location information is included.
Infiltration
Expansion: A subcategory of urbex concerned with accessing active or semi-active (not abandoned) structures without authorisation - buildings under construction, operational underground systems, rooftops of skyscrapers. Has a different legal configuration from exploration of abandoned sites.
Draining
Expansion: Drain Explorer - exploration of urban drainage infrastructure. A subcategory dedicated to the exploration of underground urban drainage systems: culverted waterways, sewer collectors, hydraulic cavities. Requires specific equipment for wet, confined environments and competences in hydraulic risk assessment.
Spelunking (Cave Urbex)
Expansion: Urban spelunking - exploration of artificial underground cavities. Overlaps with urbex in its "underground" component: bunkers, medieval cellars, unofficial catacombs, military tunnels. Requires speleological competences for assessing collapse and asphyxiation risks.
Rooftopping
Expansion: The exploration of rooftops of tall buildings. A subcategory of urbex focused on accessing the rooftops of buildings, often still active. Has specific fall risks and a more complex legal configuration than exploration of abandoned sites.
PPE
Expansion: Personal Protective Equipment. Recommended equipment in environments with asbestos, mould, or chemical contaminants. FFP2/FFP3 use is recommended in any decommissioned industrial site.
GPS Lock
Expansion: The practice of not recording or sharing GPS coordinates of a site. The automatic geotagging function of smartphones should be disabled before photographing sites intended to remain confidential.
Spoil List
Expansion: A list of sites whose addresses have been made public (often without community authorisation). A site on the "spoil list" is considered compromised and at risk of accelerated vandalism or forced closure.
Night Vision (NV)
Expansion: Equipment for light amplification or thermal imaging used in some nocturnal exploration experiences. Rare in mainstream urbex but present in more specialised subcommunities.
RCP (Responsible Capture Protocol)
Expansion: A set of documentation practices within the community emphasising non-invasive, non-identifying, and non-facilitating documentation - no access details, no GPS, no names of real sites, no instructions for entry.
