Travelling across rural Ireland from the east to the west, one thing that arouses curiosity among many first time visitors is the hundreds of miles of stone walls that meander across farmlands in all directions as far as one can see.
These stone walls are nothing odd or unusual for the Irish population, but visitors question about them a lot.

This famous blue limestone is found all over the country and it lies under more than half of the island.
