FORTWILLIAM covers 2.6 km² in Northern Ireland. With 3 historic sites and 1 scheduled monument on record, the ward sits at the 40th percentile across all 462 NI wards for combined archaeological heritage. It also records 26 listed buildings (HED Historic Buildings Record), the 57th percentile for listed-building density across NI wards. Per 1,000 residents, this works out at 6.6 recorded sites — the 40th percentile across NI wards (a measure of heritage density relative to current population). Dated archaeological evidence runs from the Early Medieval 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 FORTWILLIAM
Of the 3 historic sites recorded, the most common are Souterrain & Enclosure (1, 33% of historic sites), Holy Well: Fortwilliam (1), and Artillery Fort: Fort William (1). For Souterrain & Enclosures, this is the 0th percentile across NI wards that record this type. For Holy Well: Fortwilliams, this is the 0th percentile across NI wards that record this type. Across the ward's 2.6 km², this gives a recorded density of 11.54 sites per km² (all heritage types combined).

Chronological distribution
Terrain and environment
Mean elevation of 33m sits around the NI median (26th percentile). Mean slope is 3.4° (31th percentile across NI), giving moderately undulating terrain. The Topographic Wetness Index of 10.8 (68th NI percentile) indicates moderate drainage, balanced between upland shedding and lowland accumulation. The land-cover mosaic combines urban land (61%), woodland (32%), and improved grassland (7%), 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 Mesozoic era (Triassic period). Rock formed during the age of dinosaurs; in NI this typically appears as Triassic mudstones and Jurassic clays now buried beneath younger deposits. Bedrock composition is uniform (complexity index 0.05), with a single dominant geological unit underlying most of the ward. A uniform geology narrows the natural lithic-resource base available to past inhabitants.
Placename evidence
Just two placenames are recorded for this ward in the combined OSNI, Logainm NI, and GeoNames sources. That is too few to support any meaningful characterisation of the linguistic heritage layers — diagnostic categories such as ecclesiastical, defensive, or Plantation-era names need a larger sample to be reliably distinguished from the generic Gaelic landscape vocabulary that is common throughout Ireland.
Scheduled monuments in FORTWILLIAM

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.
