J3145 : Slieve Croob Triangulation Pillar

taken 10 years ago, 4 km SE of Finnis, Co Down, Northern Ireland

Slieve Croob Triangulation Pillar
Slieve Croob Triangulation Pillar
Trig pillar at the summit of Slieve Croob in County Down. The pillar, sitting at about 534m, is easily accessible via the walk from the car park on the Dree Hill Road. The pillar sits beside a small summit cairn. Views are fantastic in all directions, even on this hazy day - this is the view of the pillar from the cairn looking over a distant Strangford Lough but I could also see all of the Ards Peninsula and eastern County Down, the Mourne Mountains, Belfast and the Antrim hills, Lough Neagh and East Tyrone and into Armagh.

OSNI Triangulation Stations

The re-triangulation of Northern Ireland by the Ordnance Survey Northern Ireland began in 1950. This was the first complete survey of Northern Ireland which included observations with the new primary triangulation of the country, its connection with the Republic of Ireland and the cross-channel connection between Ireland and Great Britain. This began by OSNI establishing a series of triangulation stations throughout the country. Almost all of these stations were topped by trig pillars and 80, mainly primary and secondary pillars, had been constructed by October 1949. Measurements between primary stations began in 1950 and measurements for these and the secondary stations were completed by July 1956. The construction and measurements for tertiary stations were completed later (probably no later than the mid 1960s). Only two stations are not topped by pillars - Lighthouse Island, marked by a brass rivet, and Ardglass, which utilised the top of a high stone folly. The older triangulation stations on the Lough Foyle Base Line were also re-surveyed as part of this process. A majority of the stations are still extant today but a few have been removed or destroyed.
