In the excavation pit, experts continued to discover many types of bricks decorated with images of chrysanthemums, lotuses, gerberas, Ly-Tran dynasties, various types of square bricks, rectangular bricks, and decorative bricks with Chinese characters produced in the Ho Dynasty Citadel similar to previous excavations. In addition, there are relics decorated with dragon images, tile pieces with images of double lotus flowers, and quite a few pieces of glazed pottery from the Tran-Ho and Le So dynasties.

The excavation has clarified the current status of the structure and construction materials of the royal road in the inner citadel, contributing to understanding and identifying the overall structure of the Ho Dynasty Capital.
