Among the several ruins of the Great Wall in Beijing (Peking), the wall constructed during the Ming Dynasty is visited by many tourists
Unlike the fortifications of the Great Wall built during the Qin Dynasty (221 BCE-206 BCE), wall construction during the Ming Dynasty (1368 CE to 1644 CE) was more elaborate and stronger. Bricks and stones were used instead of packed earth. Due to continued attack by the Mongols and the Jurchen, the Ming rulers devoted ample resources for the repair and reinforcement of the Great Wall. Sections of this wall closest to the former Ming capital of Beijing were very strong. Today the stretch of the wall near Beijing is over 373 miles long and contains about 71 passes, 827 city wall platforms and several towers.
