Visit Notes

Sunday, 4th August 2002

I didn't realise that I was going to drive past this. The road must have moved since the OS was drawn up, so it was a pleasant surprise. Rath Crauchan or Rath Mor is reputed to be the inaugoration place of the kings of Connaught and is the centre of a huge 'citadel' covering 2 square miles.

The only real interest here, though, lies in its history. To be able to stand in the same place as the ancient kings is quite special, knowing that great things (many probably bad) were put in motion here.

The rath, like all raths, is just a banked mound but of considerable height at 3m tall. It is at least 35m in diameter. There is so much in the area related to this site that a more dedicated visit is needed to see the ancient roads, barrows and the standing stone that is supposed to mark the burial place of the last king of Ireland.

Monument 4 of the Megalithomania 2010 Meet Up. They rain started to ease a little when we reached this site and it was the last we were to see of it all day.

The preservation of this mound, like most of the monuments in this area is great. The ditch around the base is still visible, but is clearly silted up. It would have been quite deep when first cut. The one odd/interesting thing about this barrow/mound is the presence of two causeways across the ditch. What's really odd is the fact that only one of them seem to lead to any kind of entrance to the top. Did they build one in the wrong place and leave it there? Or is there a purpose to the second 'blind' causeway?

Rath Mor means the Big Rath, but it is more likely that this is a large barrow that was reused as a rath at a later date.

About Coordinates Displayed

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.
