Xiyu Ammunition Depot Introduction
National Historic Site of Xiyu Ammunition Depot Military Cultural Park. The Xiyu Ammunition Depot, as the name suggests, was primarily used for storing artillery ammunition. The cave-style ammunition depots come in two types: single-cave and double-cave, storing two different types of gunpowder—smokeless and smokey. The cave ammunition depots feature a double-walled, arched structure. Initially, a circular arched cave is excavated on the rock surface of the mountain, with concrete blocks stacked to form the outer structure, and the inner space built with reinforced concrete to store smokeless gunpowder. In addition to maintaining constant temperature and humidity, the side walls are covered with copper plates to completely isolate electromagnetic pulses and moisture. As for the soil cave-style ammunition depot, it is an above-ground structure, with the exterior walls made of stone and the interior walls made of wooden panels along with elevated wooden floors for moisture prevention. The rafters are constructed using steel trusses, and the roof is covered with cultural tiles, which are blackened tiles. The roof is also equipped with lightning rods for protection against lightning strikes. Both types of ammunition depots are rare military buildings from the early Japanese colonial period in Taiwan, showcasing the architectural techniques of that time, and have been designated as county historic sites for restoration and preservation.
