A 1 to 50 scale model was done in the early 20th century. The original temple was larger and had to 100 meter pagoda's on either side of it. The pagoda's were at the time, the tallest structures in the world outside the pyramid's of Egypt. The pagoda's were destroyed by an earthquake.
This pillar with a hole in the base is considered good fortune if you can fit through it (enlightenment in your next life). The hole is the same size as one of the nostril's as the Daibustu of Todai-ji.
