Ashley, Qin Empire wasn't the first one to build the wall. It was originally built in 656 BC. Until the Ming Dynasty, the construction still continued. However, it was almost stopped in Qing Dynasty. So you can see that the construction finished in Ming Dynasty. Ming Dnasty ended in 1644. Then you can figure out that it took around 2300 years to build the wall.
