Bench Mark

Bench marks LinkExternal link were historically used to record the height above sea level of a location as surveyed against the Mean Sea Level data (taken at Clarendon Dock, Belfast, for Northern Ireland data, Newlyn in Cornwall for data in Great Britain and Portmoor Pier, Malin Head, for data relating to the Republic of Ireland). They were used as part of a greater surveying network by the UK Ordnance Survey, Ordnance Survey Northern Ireland (OSNI) and the Ordnance Survey Ireland (OSI). If the exact height of one bench mark is known then the exact height of the next can be found by measuring the difference in heights, through a process of spirit levelling. In this way hundreds of thousands of bench marks were sited all around the UK & Ireland from the mid 19th to late 20th centuries. There are several distinct types of bench mark:

- Fundamental bench marks have been constructed at selected sites where foundations can be set on stable strata such as bedrock. Each FBM consists of a buried chamber with a brass bolt set in the top of a granite pillar. See NG8825 : Dornie fundamental bench mark for an example. FBMs were used in Ireland as well as GB but those in Ireland do not have any surface markers, nor are they marked on standard maps.
- Flush brackets consist of metal plates about 90 mm wide and 175 mm long. Each bracket has a unique serial number. They are most commonly found on most Triangulation Pillars, some churches or on other important civic buildings. See J3270 : Flush Bracket, Belfast for an example.
- Cut bench marks are the commonest form of mark. They consist of a horizontal bar cut into a wall or brickwork and are found just about anywhere. A broad arrow is cut immediately below the centre of the horizontal bar. See J3372 : Bench Mark, Belfast for an example. The horizontal mark may be replaced by or contain a bolt - see J1486 : Bench Mark, Antrim.
Other marks include:
- Projecting bench marks such as SD8072 : Projecting Bracket Benchmark on St Oswald's Tower
- Bolt bench marks such as SJ1888 : OSBM bolt on Hilbre Island
- Rivet bench marks such as J3978 : Bench Mark, Holywood
- Pivot bench marks such as SJ2661 : Pivot bench mark on Leeswood Bridge

Bench marks are commonly found on older buildings or other semi-permanent features such as stone bridges or walls. Due to updated mapping techniques and technological advances such as GPS, bench marks are no longer maintained. Many are still in existence and the markers will probably remain until they are eventually destroyed by redevelopment or erosion.

Church of St Mary, Longframlington :: NU1300

A simple church consisting of unaisled nave and chancel of Norman origin, with later south porch, vestry and community room. It was a chapel of ease to the mother church of St Michael, Felton, before becoming a separate parish in 1892. The parish also includes the priory church of Brinkburn.

The nave is largely still the Norman structure of around 1190, although the window opening were renewed during the Victorian restoration. The chancel arch, the detached pillars of which are unusual, is also of this period.

The porch is probably 14th century, but was rebuilt incorporating older material, including the main arch, in 1749. The west end was remodelled at around the same time when the bell turret was added.

The chancel was rebuilt in 1882, and the vestry added in 1896. The latter incorporates a 14th century two-light window which is thought to have been in the south wal of the chancel. In 2012 a community room was added to the north side of the church.

Inside, the chancel arch is the main item of interest. There is also an unusual piscina in the chancel, clearly of old date and built into the new wall, consisting of a basic bracketed out from the wall, rather than being recessed or in the windowsill.

The church is Listed Grade I.
