In the 12th century, the King of France decided to build the famous Saint Denis Cathedral as a place for pilgrimage and royal burial. At that time, Dean Su Re decided to fill the interior of the building with the radiance of the Celestial Kingdom, to enhance the spiritual connection between individuals and the Celestial God, making it feel as if mortals were walking in the kingdom of God.
For the first time in history,
Large-scale stained glass was used in the building, and Saint Denis Cathedral became a milestone in architectural history, still synonymous with the ornate complexity of French architecture.
As a medium separating humans and the divine realm of the Celestial Kingdom,
even those experienced master painters, when facing stained glass windows, would ponder carefully before making a move.
