A path for one
The Raised height has its significance
During my trip to Seoul, I visited the Gyeongbokgung palace. Seoul is a city which is abundant in heritage and traditional culture. The Gyeongbokgung palace is the largest built out of the five other palaces during the Joseon Dynasty. What I learned about this royal palace is that when you enter the main ground, you will see three long pathways built of stone that leads to stairs to ascend into the building. The path in the middle is raised the highest and only the King was allowed to walk on that path. The two other paths at left and right are slightly lower in height and was accessible for the assistants to walk on. To this modern day however the paths are open for visitors to walk on and there are no restrictions as to which path you are allowed to walk on.
This is another palace in Jeonju the path is more prominently raised with left and right paths aligning the far perimeter of the palace.
