What can you say - Teltown, the site of the famed or, more correctly, infamous Teltown festivals. These ran from a very early, unknown date until the early 1800s when they were stopped by the church.

Rath Dubh is a huge fort about 80m in diameter. The central platform is about 4m about the level of the field around it. In several places the banks around the rim of the platform rach 1.5m high.

What truly shocked me is the view to the northwest. Looking this direction you can actually see Loughcrew!!! What a great spot to build what must have been a Royal Rath - within site of an ancient cemtery, which probably featured strongly in the lore of the people that built Rath Dubh.

From Kells follow the N3 south towards Dublin. Around 4.5km out of Kells Teltown is signposted on the left. Follow this road until it reaches what at first appears to be a t-junction. Look to your right and you will see another road that runs down the side of the school. Take this road and then take the first right. After about 400m you will see a large white house on the right. Rath Dubh is in the field behind this house.

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.
