How is sacred space created in a religious building through decorations and architecture?

The religious building that I visited was Canterbury Cathedral. The architecture of Canterbury Cathedral really stood out to me as the thing that created sacred space the most. The Cathedral was so large yet the architecture was so intricate and detailed. That for me, is like God in a way, being so big but also being so detailed and complex in the making of his creation. So, if people looked at it in that way it might help them consider it as more of a sacred space. There are also lots of gold crosses in different parts around the cathedral. The cross is a sacred object for Christians and Catholics alike. It symbolises that Jesus died on the cross for the sins of the world, but he did not stay there, but he rose again. So Christians keep the cross as a reminder of the sacrifice that Jesus Christ made for anyone who believes in him. The stain glass windows are another thing that is found mainly in churches and cathedrals. They often have pictures of Jesus, The Virgin Mary (mother of Christ) and the archangel Gabriel. These windows surrounding the rooms often help people to connect with God. These things along with many others help make Canterbury Cathedral a sacred space for many.
