The published co-ordinates bring you to the Saints and Scholars school - on the sign outside is a year, the last digit = A
Stage 2 is at St Aidan's Church in Salters Grange just outside the city, you have a choice here, the last digit of the time for Sunday Service or the 2nd digit on the fire hydrant to the left of the gate as you look at the church from the road outside = B
The reason for the choice is that sometimes the gate into the church is closed, not locked but incase anyone doesn't want to open it. (also you are very close to a cache that puzzled us for sometime - The Bloody Oak GC3AM0J worth a look if you haven't already got it)
Stage 3 is at St Patrick's Primary School, on the sign outside there is a telephone number, the last digit = C
Stage 4 is at St Malachy's Chapel, not being able to place a cache here was the inspiration for this puzzle. There is a date on the front of the chapel, the 2nd digit = D
Stage 5 is at St Mark's Church, all the way up the avenue! Again there is a date on the front of the church, the last digit = E
The final co-ordinates are N54 20.(A+B)C(D-E), W006 37.CBD
The final cache is hidden just outside the city, and is medium sized screw top camo'd container There is parking nearby at all the stages, for the churches maybe avoid service times and starting and finishing times at the schools. Don't forget to check out all the other caches in Armagh, the journey for this puzzle passes quite a few!!
