The new surface around the altar is laid out in the form of a labyrinth, as laid out in mediaeval cathedrals. In the Christian tradition, a labyrinth represents the path of Christian life, this path was walked at significant times, such as on the eve of baptism or confirmation, or during Holy Week. This particular design is based on a design by Michelangelo, which, in additional to being a labyrinth that is a continuous line, has the appearance of being a twelvepoint figure. The symbolism of Christ on the altar of sacrifice is central and the twelve points represent the twelve-point represent the twelve apostles. The materials used are Irish limestone, polished to appear dark and Italian white marble. Irish Natural Stone of Boston, Co. Clare have supplies and laid the stone.
