The Pius Church in Meggen, Switzerland, is renowned for its extensive use of Pentelikon marble. One of the most striking features of the Pius Church is the unique use of 28mm thick Pentelikon marble panels. These panels allow light to penetrate through the marble, creating a stunning effect similar to that of a marble glass window. The natural translucency of the marble enhances the light, casting a soft, ethereal glow throughout the interior of the church. This interplay of light and marble not only highlights the intrinsic beauty of the material but also elevates the spiritual ambiance of the space, making it a place of contemplation and tranquility.
