长城词典·九门口关九门口关在山海关城北15公里处，建于冀辽交界的九江河上，城与桥融为一体，桥身八墩九孔，故名“九门口”。关城建在面积约7000平方米的由条石铺就的河床上，条石间有铁榫石铆相咬合，所以又称一片石关。城西九江河南岸有一座子母相依的烽火台，又称“将军墩”。台顶生长着一棵数百年的大松树，非常奇特。九门口曾经硝烟弥漫，发生在山海关的战役，这里多是重要的战场。 Great Wall dictionary·Jiumenkou PassLocated 15km north of the town of Shanhai Pass，Jiumenkou Pass is built on Jiujiang River，which straddles Hebei Province and Liaoning Province.
