Another place that I have tried to visit a few times, but due to it being at the rear of someone's house and them never having been at home when I've called I have not, until today, succeeded.
It was worth the wait. What a magnificent stone this is. Unfortunately, it lies recumbent after having fallen around 1900. The stone is one of the most phallic I have come across to date and at over 4m long it must have been amazing when standing up.
It offers a little mystery too, which is always nice. The stone is broken at both ends (so how tall was it?) and has some cup marks around the thicker end. However, there are also two crosses carved upon it and these would be upside down if the stone was stood up with the thicker end at the base. So, were the crosses added whilst it was fallen or did the stone stand the 'wrong way up'?
The stone is so amazing and its presence must have really meant something to the locals because it gave its name to the whole townland - Longstone. It is also next to Longstone Farm.
The land owner is quite proud of the stone and rightly so. His family have owned the land for some time and he told me a tale of his father digging a hole along the ridge upon which the stone stands and finding some granite burial chambers about 4 m down.
This is an explanation of (and a bit of a disclaimer for) the coordinates I provide.
Where a GPS figure is given this is the master for all other coordinates. According to my Garmin these are quite accurate.
Where there is no GPS figure the 6 figure grid reference is master for the others. This may not be very accurate as it could have come from the OS maps and could have been read by eye. Consequently, all other cordinates are going to have inaccuracies.
The calculation of Longitude and Latitude uses an algorithm that is not 100% accurate. The long/lat figures are used as a basis for calculating the UTM & ITM coordinates. Consequently, UTM & ITM coordinates are slightly out.
UTM is a global coordinate system - Universal Transverse Mercator - that is at the core of the GPS system.
ITM is the new coordinate system - Irish Transverse Mercator - that is more accurate and more GPS friendly than the Irish Grid Reference system. This will be used on the next generation of Irish OS maps.
