West Emplacement was built in the 8th year of the reign of Guangxu during Qing dynasty and completed six years later. It is an important fort of coastal defense along the coast of Northeast Region of China, invested by North Sea Naval and constructed by Qing government. It became the most important project of the coastal defense in Northeast Region during the modern time, which was enlisted into Provincial-level key cultural relics-preservation institution in 1963.
The emplacement is made of mortar which is a mixture of sand soil, lime loess and water. The complex is composed of emplacements, trench, wall, gate, shade wall, reservoir, water cave, drawbridge, arms house and barrels, etc. There are three emplacements all together, one is large and the other two are small. They are rectangles in shape. The large one is in the middle, standing six meters high and including three storeys. The uppermost is a plat form rimmed with low walls. The four walls are symmetrical, where there are eight hidden holes under. Along the east of the emplacement stretches a slopped path, about 62 meters long and 9 to 12 meters wide, facing the main gate in east. There are two minor emplacements beside the main one, 35 meters apart, In the east of which respectively come two slopped paths, 24 meters long and 4 meters wide, leading to another two small emplacement upwards and downwards. Around the main emplacement stands an enclosing wall, in a shape of the Chinese character 凸, stretching more than 1000 meters long and 5 meters high. On both sides sand and limes are heaped up as protection. The enclosing wall is encircled by a trench, 8 to 12 meters long. In the east of the enclosing wall are two small gates and one big gate in the middle, respectively facing a shade wall in a distance of 30 meters away. All are made of rammer soil. The one in front of the big gate seems extremely high and heavy. The emplacement played a very important role during the Sino-Japanese War of 1894. Utilizing it, the seamen of Qing dynasty guided by Qiao Gan, a naval officer in the coastal defense training camp, blocked and brought a heavy blow to the Japanese invaders. In the process of sort-out in 1991, above one hundred relics and the previous building remain were found, such as iron cannons, artillery shells, foreign bullets, iron, the equipment for tamping wall, bronze bricks, plinths, drip-tiles, porcelain pots, bowels, dishes, spoons and tinkling bells on a caving and so on.
