Bench Mark
Bench marks 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 Due to updated mapping techniques and technological advances such as GPS, bench marks are no longer maintained.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 Peter, East Drayton
The church consists of nave with north and south aisles, chancel, west tower and south porch. The overall appearance is of a complete Perpendicular style church but some fabric remains from the 12th century.

The exterior is largely 15th century work, the most notable earlier feature being the late 12th century Norman doorway in the north wall of the chancel. The elegant west tower, unlike many neighbours, is of a single period, with a 3-light west window and 2-light bell-chamber openings. The 15th century south porch is noteworthy for the set of 6 crocketted pinnacles and the ribbed vault of its roof. Inside it also contains a small image niche over the remains of a stoup. The north aisle has been reinforced with plain coursed rubble buttresses at some period.

The nave comprises two 4-bay arcades of the 14th century (north) and 15th century (south), with a 15th century clerestory. The chancel arch is flanked by stone angels with a third at the apex. A similar angel surmounts the tower arch. The nave roof timbers are 15th century with carved bosses. There is a fine 15th century timber chancel screen, but other interior furnishings are 19th and 20th century. There are interesting paintings - 'cake-rings' or 'cheeses' - in the ringing chamber of the tower, celebrating weddings and dated between 1769 and 1865.

The church is Listed Grade I. For more information about the church see the Southwell & Nottingham Church History Project LinkExternal link
