The windows

Gothic numeric mysticism

The 2-aisle Catholic parish church is completed in its present form in 1520, the interior is finished earlier in 1505. If you observe the narrow windows of the choir - the part of the church where the 2 side-aisles become one - from the lake side, you will discover typical Gothic variations of trefoils and quatrefoils. These are the segments of circles you see in the upper part of the window; known as trefoil when split into 3 and quatrefoil when split into 4.

The trefoils and quatrefoils expose a little of the mystic rules behind medieval architecture. The length and breadth of sacred buildings often correspond to the numbers 3 and 4. 3 stands for the divine, 4 for the earthly.
