Answer 1

On the off-chance that this question might be

* Why did the ancient Irish build High Crosses

I'll answer

The ancient Irish were a largely illiterate people with a strange alphabet called Ogham which was mainly sued to inscribe brief "messages" on stone.

The Church used the High Cross as a teaching aid. The designs depicted on the body of the cross were usually scenes from the Gospels, although there were some Old Testament events recorded also. The crosses would have been used for religious instruction. Stone was plentiful and the craftsmen skilled. Some of the crosses held great detail and stood for many years, totally exposed to the elements.
