![]() There are no National Parks in this county but is does have some very interesting place names. The county actually extends south to the River Tees, which serves as the boundary for much of its length, and out to the west, into the Pennines. The City of Durham lies to the very north of it. I never really thought about how big County Durham is. It was that way until 1974 when it all became Tyne & Wear and I ceased to be a resident of County Durham. ![]() When I was very young and first learned my address, it was in County Durham.

One way to remember which comes first is to remember ‘Along the corridor and up the stairs’ – reminding you to give the figure along from the vertical line and up from the horizontal.Īnother common mistake is to give the wrong 100km two letter reference (SP instead of SU or vice versa). ![]() These two numbers (4 and 2) are written as the third and sixth numbers in your six figure grid reference.Įven people who are very used to grid references occasionally get them ‘back to front’ – this is when you give the northing before the easting instead of correctly giving the easting before the northing. 4 sub-divisions to the east and 2 sub-divisions to the north. You need to count how many subdivisions to the east of the nearest vertical 1km line and how many 100m sub-divisions north of the nearest horizontal 1km line your spot is e.g. To work out a six figure grid reference you need to sub-divide a 1km square into 100m squares – these sub-divisions are marked on the outside edge of a 1:25,000 Explorer map, but they are not numbered. You can give a four figure grid reference by writing the 100km letter code (SP) followed by the number of the vertical line running down the left hand side of the 1km square (the easting) and then the number of the horizontal line running along the bottom of the 1km square (the northing). ![]() Each one of these lines is labelled with two numbers. In Oxfordshire and Berkshire the codes are either SU (Berkshire and south Oxfordshire) or SP (north Oxfordshire) with a small part of TQ (eastern-most part of Berkshire).Įach 100km square is divided into 1km squares and these are the lines that you see on an Ordnance Survey map. This code forms the first part of your grid reference. The UK is divided into 100km squares by the Ordnance Survey and each 100km square has a two letter code (see map). It is easier to work out an accurate grid reference using a 1:25,000 (4cm to 1 km / 2 ½ inches to 1 mile) Explorer map (the ones with the orange cover) rather than a 1:50,000 (2cm to 1km / 1 ¼ inches to 1 mile) Landranger map (pink cover). If you don't know the grid reference, you can find it using .Īlternatively, you can use any Ordnance Survey map to work out a grid reference. ![]()
