Past military conflicts in Kinmen, the one-time frontline in defense of the main land of Taiwan and Penghu Archipelago, leave the Island much evidence of it. Defensive facilities and after-war memorials scattered around the island virtually turned the small land into a battlefields space, silently speaking of the pivotal role in once played ; meanwhile they now serve as convincing monuments powerfully pleading world peacefulness.

The remote Kinmen Island was at a disadvantage in military conflict. Luckily, its uplift structure composed of a composition of granite and granite gneiss enables underground construction. Starting from 1956, military stations and posts were first laid out beneath the ground, marking the beginning of the establishment of subterranean world. Since then, military facilities were progressively moved below ground through out the entire period of the odd-dated bombarding. Canals were built in 1963in Jhaishan(翟山)and Jiougong(九宮) to facilitate sealift supply. Cingtianing Hall(擎天廳)was subsequently constructed in 1962,followed by the accomplishment of the Granite Hospital and the Reception Hall a tunnel hotel, in 1978.Local resident were busy in constructing air defense basement in or hear their houses. From 1976 on ward,a series of project were aimed to bring a majority of village facilities underground, such as those in Cyonglin and Jincheng.

From a battlefield of Nationalist-Communist conflicts to political arena during Cold War and an isolated military output, Kinmen has its significance in the modern history .As flames or war have faded with time, what was left behind, however ,are sites and traces of the past, uttering the shattered old times and momeries of historic events.
