Ornamental metals, made by Echizen forging technology for cutlery, are attatched to the doors of two front entrances of the Main Hall. Metal, in which copper and brass are mutually laid by the forging technology in Takefu City, was shaven into small hemispheres. These small hemispheres were attached to the surface of the doors at 20cm intervals, so at a glance, they look like a myriad of small planets floating in the cosmos.
