明长城龟山段
位于辽宁省锦州市凌海市
据文献记载，该段长城始建于明正统二年（1437年）至成化七年（1471年）。该段长城墙体由夯土外包石墙体、山石垒砌墙体和山险墙组成，辽东镇长城的三种建筑形式在这里均有体现。考古调查还发现了居住址、采石场、石臼等遗存，为研究辽东镇陆上军事防御体系提供了实证依据。
The Great Wall of the Ming Dynasty in Guishan
Mountain
It is located in Linghai, Jinzhou City, Liaoning Province. It is recorded in some historical documents that this site was constructed from the 2nd year of Zhengtong of Ming (1437 A.D.) to the 7th year of Chenghua of Ming (1471A.D.). The walls were built with the rammed earth covered and enfolded by a layer of gravels outside, or with mountain stones stacking layer upon layer, or with the integration of the natural terrains. These three methods were commonly adopted in the Liaodong Great Wall. Through the archaeological endeavours, some remains of dwellings or quarries and some relics like stone mortars were found, offering practical evidence to researchers with the defence system in Liaodong Area.引自 明长城
