Round walls were harder to knock down than right angled walls. If you hit a round wall not much damaged would be made but a right angled wall would cave in.
Castle (or other walls) are called concentric if they form a series of (very roughly) cirular walls round one centre. By the late Middle Ages major castles in Europe often had three walls round a central keep.
The walls of the castle are 18ft thick. So arrows can't break through the castle. I got this answer from http://www.pennyparker2.com/blarney.html. But its very scary walking round the top as the building is very high and all the inside has collapsed.
The type of castle that has two walls around it is called a concentric castle. ferocious

A Round Keep was one of the strongest castle designs. A round tower would not have any sharp corners that prevented the view of the archers. It would provide a broad view for the soldiers. There would also not be any weak corners that the enemy could tunnel under and collapse a wall. Also, a Round Tower would allow enemy missiles to bounce and slide off the smooth walls.

Blarney Castle has a total of three defensive walls. These walls were constructed to protect the castle from potential invaders and to enhance its fortifications. The design reflects the castle's historical significance and strategic importance during its time. Today, these walls contribute to the castle's charm and appeal as a tourist attraction.
