Henk The Great Wall of China "The long wall of 10,000 Li is a series of stone and earthen fortifications in China, built between 5th century BC and the 17th century to protect the northern borders of the Chinese Empire during the rule of successive dynasties. Several walls, referred to as the Great Wall of China, were built since the 5th century BC, the most famous being the one built between 220 BC and 200 BC by the first Emperor of China, Qin Shi Huang; this wall was located much further north than the current wall built during the Ming Dynasty, and little of it remains. The Great Wall concept was revived again during the Ming Dynasty, following the Ming army's defeat by the Mongols in the Battle of Tumu in 1449. The Ming had failed to gain a clear upper-hand over the Mongols after successive battles, and the long-drawn conflict was taking a toll on the empire. The Ming adopted a new strategy to keep the Mongols out, by constructing walls along the northern border of China. Acknowledging the Mongol control established in the Ordos Desert, the wall followed the desert's southern edge instead of incorporating the bend of the Huang He. Unlike the earlier Qin fortifications, the Ming construction was stronger and more elaborate due to the use of bricks and stone instead of rammed earth. As Mongol raids continued periodically over the years, the Ming devoted considerable resources to repair and reinforce the walls. The sections near the Ming capital of Beijing were especially strengthened. Towards the end of the Ming Dynasty, the Great Wall helped defend the empire against the Manchu invasions that began around 1600. Under the military command of Yuan Chonghuan, the Ming army held off the Manchus at the heavily fortified Shanhai Pass, thus preventing the Manchus from entering the Liaodong Peninsula and the Chinese heartland. The Manchus were finally able to cross the Great Wall in 1644, when the gates of Shanhai Pass were opened by Wu Sangui, a rebel Ming border general. The Manchus quickly seized the Ming capital of Beijing, and subsequently defeated the remaining Ming resistance to establish the Qing Dynasty. Construction and repairs of the Great Wall were discontinued under the Qing rule, as China's borders extended beyond the walls and Mongolia was annexed into the empire. The Great Wall is one of the existing megastructure and the world's longest man-made structure, stretching over 6,352 km (3,948 miles) from Shanhai Pass in the east to Lop Nur in the west, along an arc that roughly delineates the southern edge of Inner Mongolia. The following three sections are located in Beijing Province where reconstruction has taken place and which are regularily visited by modern tourists:
