The Great Wall is a series of military constructions that are made of stone, tamped earth, brick, and wood and are constructed along the historic northern border of China to protect the Chinese states against raids and invasions of nomadic groups along the Eurasian frontier. The building of this wall began in the early 7th century BC.
Juyongguan is found in the Guangou valley of Changping District, a distance of 50 km from Beijing. The pass stretches down the valley and has beautiful surroundings, built during the Ming Dynasty.
