 But apart from the Forbidden City, whose walls remain well-preserved, city walls from the Ming Dynasty have suffered wholesale demolition in the decades since.The only surviving sections are Qianmen's gate and arrow tower, Deshengmen's arrow tower, a section of the wall and Southeast Corner Tower preserved in the Ming City Wall Relics Park, and the Xibianmen corner tower.The Yongdingmen Gate was rebuilt in 2005.
