LAGAN VALLEY covers 3.1 km² in Northern Ireland. With 3 historic sites and 1 scheduled monument on record, the ward sits at the 21st percentile across all 462 NI wards for combined archaeological heritage. It also records 6 listed buildings (HED Historic Buildings Record), the 22nd percentile for listed-building density across NI wards. Per 1,000 residents, this works out at 3.1 recorded sites — the 26th percentile across NI wards (a measure of heritage density relative to current population). Dated archaeological evidence runs from the Mesolithic through to the Post-Medieval period, spanning 2 archaeological periods, the 22nd percentile across NI wards (a relatively narrow chronological band).

Population context
The recorded heritage of LAGAN VALLEY
Of the 3 historic sites recorded, the most common are Standing Stone?: Longstone Lane (Placename Evidence Only) (1, 33% of historic sites), Workhouse (1), and Workhouse Burial Grounds (1). For Standing Stone?: Longstone Lane (Placename Evidence Only)s, this is the 0th percentile across NI wards that record this type. For Workhouses, this is the 0th percentile across NI wards that record this type. Across the ward's 3.1 km², this gives a recorded density of 3.23 sites per km² (all heritage types combined).

Chronological distribution
Terrain and environment
Mean elevation of 41m sits around the NI median (32th percentile). Mean slope is 3.9° (43th percentile across NI), giving moderately undulating terrain. The Topographic Wetness Index of 10.7 (63th NI percentile) indicates moderate drainage, balanced between upland shedding and lowland accumulation. The land-cover mosaic combines urban land (54%), woodland (27%), and improved grassland (19%), giving a mixed agricultural and semi-natural landscape.
Terrain measurements
Where this ward sits in NI
Geology and preservation
The dominant bedrock formed during the Palaeozoic era (Permian period). Ancient sedimentary or metamorphic rock dating to before the age of dinosaurs; the resulting landscape has been long-stable enough to host every period of human activity. Bedrock composition is varied (complexity index 0.87, on a 0-1 Simpson-style scale), with multiple geological units within the ward boundary. Geologically diverse wards historically offered a wider range of stone types for building, toolmaking, and quarrying — a relevant factor when interpreting the material culture of nearby sites.
Placename evidence
The placename record for this ward is small — 4 names in total — but it does include 2 pre-Christian defensive placenames. With this few records, the count should be treated as indicative rather than a firm characterisation.

About this profile
What is a ward?
A ward is the smallest electoral and statistical geography used by the Northern Ireland Statistics and Research Agency (NISRA). The boundaries used here are the 2014 NISRA / OSNI Wards (462 across Northern Ireland), each typically covering 1-700 km² and a population of a few thousand. Wards do not align with parishes, townlands, or any historic administrative unit — they are a modern statistical convenience, used here only as a fixed spatial frame within which to summarise heritage records.
What counts as a site?
Three distinct heritage record types are reported separately, not combined: (1) Historic Sites — entries in the Northern Ireland Sites and Monuments Record (NISMR), the inventory of recorded archaeological sites and findspots, dated from prehistoric to early-modern; (2) Scheduled Monuments — sites legally protected under the Historic Monuments and Archaeological Objects (NI) Order 1995 and maintained by the Historic Environment Division (HED); (3) Listed Buildings — buildings of architectural or historic interest protected under the Planning Act (NI) 2011 and graded A, B+, B1, B2, or Record-Only by HED. A site appearing in more than one register is counted in each register independently.
Editorial principles
These ward profiles describe evidence, not history. They report what is recorded, not what occurred. Where the data is ambiguous, we say so. We do not infer historical processes — population movements, settlement expansion, periods of decline — from patterns in the record. Absence of evidence is not evidence of absence: in Northern Ireland, where antiquarian survey was uneven and modern excavation is geographically biased, a gap in the record almost always reflects the limits of recording rather than a genuine historical absence. We mark such gaps explicitly where they appear in the data.
Limits of coverage and known caveats
Several caveats apply to every ward profile: (1) NISMR coverage is uneven across NI — some areas (notably parts of the south-east and the Belfast urban fringe) have been more intensively surveyed than others, so a low recorded site count does not reliably indicate a low past density of activity; (2) period attributions in NISMR are often 'Unknown', and chronological breakdowns reported here reflect only the dated subset; (3) placename classification depends on the Irish-language form (name_ga), which is recorded for approximately 50% of NI placenames in the combined sources, so ecclesiastical and pre-Christian counts may be understated where anglicised forms remain unparsed; (4) terrain percentile ranks compare each ward only to the other 461 NI wards; they are not absolute thresholds. For absence-dominant land cover categories (wetland, water, cropland), percentile ranks are suppressed below 1% raw value, since the ranking of zero-value wards is not meaningful.
