位于今天辽宁省开原市八棵树镇和李家台乡的哈达城寨遗址已面目全非,只剩下土垣而已,但这些城寨在文献上都有记载。哈达都城有三座:哈达旧城、哈达新城和哈达石城,此外哈达城寨还涉及花园城等。哈达城寨的位置及其沿革,反映了作为扈伦“正统之国”的哈达由盛到衰的全过程。 Nowadays, the Hadad Walled Ruins located in Ba Keshu Town and Lijiatai Township, Kaiyuan City, Liaoning Province, have gone beyond recognition, leaving only the wall. However, these walled villages are well documented in the literature. There are three cities in Hatta: Hatta, Hada and Hatta, and Hatta is also home to Garden City. The location and history of Hatta Castle reflects the whole process of Hatta’s rise and fall as Hulun “Orthodoxy”.
