Shamrocks are said to have been used by Ireland's patron saint, Saint Patrick who used the triple leaf to explain the concept of the Holy Trinity to the pagan Irish during the fifth century AD.
Each leaf is one but made up of three separate leaves, there are many species of small plant that grow in Ireland that could possibly be the shamrock that is referred to in the Saint Patrick story.

It can hardly be called a large country, Ireland. It's possible to drive from the Irish Sea to the Atlantic in around three hours but the backroads of Ireland are some of the most scenic it is possible to encounter.
