Amazing Celtic Cross Discovered In Irish Forest

The story behind this impressive landmark growing in the middle of Donegal Forest, in Ireland, is just as impressive. The Celtic Cross which only becomes apparent in autumn when the tree leaves change colour has been described as a feat of horticultural engineering, one which must have taken some time and some very careful planning... 

The "Emmery Celtic Cross" named after Liam Emmery, who planned the masterpiece out, planting two different types of trees 10 years ago. Liam sadly passed away 6 years ago without being able to see his creation grow and flourish. It was forgotten about since not many knew about it, however in the last year, passengers flying into Derry airport started to spot the cross. It is at least 400 feet in length and 150 feet wide and is truly a sight to behold.
