“The shape also comes from cosmological ideas, reflecting the religion of the day. It is believed to be the most perfect of all geometries, because the radii are equidistant at all points, and it is a mirror of a harmonious cosmic order. In the Catholic religion, as well as the pagan religions Catholicism supplanted, the circle is the basis of everything created. It represents perfection, as well as the cycle of life and death. What this means is that the circular shape also works to imitate nature, thus appearing to blend into the surrounding countryside instead of sticking out in the landscape the way most cities do up until this very day. The designers intent was more than mere camouflage, they meant for the city to be in harmony with the divine.”
From Feng Shui point of view there is no place to receive the Qi.
Solution: An open field like a Ming tan or bright hall followed by the entrance to the city and also a structure forming a bay in order to suck the Qi which would ideally come from a good mountain range
