The symbols of Ireland that we have come to know are often the ones associated with luck and fortune. However, not every Irish tattoo is about only luck. The shamrock, for instance, is one of the most famous symbols of Irish culture, and is more about faith than fortune. The shamrock, with its three leaves, represents the trinity of the Father, Son, and Holy Ghost.
Of course, when a lot of people think of Irish tattooing, they think of popular Celtic symbols like the Claddagh and the Celtic cross, and the intricate knotwork that goes into these designs. These make for beautiful tattoos because of the elegance of the lines and the careful amount of detail that goes into the knots.
