ShanHaiGuan Great Wall ( literally 'the Pass where the first Mountain meets the Sea') is north of QinHuangDao city and is called 'the Museum of the Construction of the Great Wall' because it features the following sections: OLD DRAGON'S HEAD (the only part of the Great Wall that meets the sea), No. 1 PASS UNDER HEAVEN (the first pass of the Great Wall), JiaShan Mountain (the first mountain the Great Wall climbs), JiuMenKou (the only part of the Great Wall in the shape of a bridge) and Meng Jiang-Nu Temple built during the Song Dynasty.
