This is quite an incredible thing to have in your back garden ... a 75m long souterrain!

I'll try and describe it:

After descending the steps you find yourself in a 27m long passage running east (all the passages are 1.5m wide and 1.5m high). The passage then turns right for 20m where it turns left and runs for 10m to a dead-end, but fear not! There's more.

Just before the dead-end there is a trapdoor in the ceiling which takes you up to another 4m long passage, which then drops back down into a 25m long passage, like a sort of vertical chicane. This passage terminates in a large room 13m long, 2m high and 2m wide, which runs across the end of the final stretch of passage.

Building this would have been a massive undertaking: certainly beyond my comprehension of time and labour scales. To make it even more amazing there are several other inaccessible souterains close by, which are just as grand in scale.

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.
