晚清时代,齐长城的许多段落尤其关隘要塞曾得到过大规模的修复,作为抵御捻军的工程。御捻长城主要集中在齐长城的西段,即今长清、章丘、博山、淄川、临朐、安丘等区段。至于御捻长城的建筑特点,除了锦阳关左右城墙筑得异常高大雄伟之外,其他多属于单墙式,既窄又矮,无论是体积规模,还是建筑技术和风格,都与古齐石砌长城迥然有别。 In the late Qing dynasty, many passages in the Great Wall and, in particular, the pass garrison had been extensively restored as a project against the Nien army. Yu twist the Great Wall mainly concentrated in the western section of Qi Great Wall, now Changqing, Zhangqiu, Boshan, Zichuan, Lintao, Anqiu and other sections. As for the architectural features of the Great Wall of Yushu, apart from the unusually tall and magnificent walls built around Jinyangguan, the others are mostly single-wall, narrow and short, both in volume and in architectural techniques and styles, Great walls are very different.
