The windows, which express Celtic culture as seen in the 9th-century illuminated manuscript the Book of Kells, inspired the goal of the renovation: to connect Celtic spirituality to contemporary Catholic worship. The project included the design of intricate, curvilinear stencils on light fixtures, elegant plaster reliefs, and stone flooring, using computer-aided design and waterjet cutting technology. A new altar and pews were created, incorporating motifs from Celtic culture at both grand and intimate scales.
