Xiyu East Fort and Xiyu West Fort were built at the same time. In the fort, they used bricks and stones to build arch-shaped ammunition dumps and living quarters for officers and soldiers. It guarded the Magong Port with Jinggui Fort. Now, Xiyu West Fort, Xiyu East Fort, and Dongchang Camp have been transferred from Penghu Defense Command. They are projected as Xiyu East Fort Military Historic Park.
