Abstract. Liugou Ancient Castle located in the southeast of Yanqing District, Beijing. It is an essential castle in the perimeter defence system of the Great Wall. The ancient castle presents a clear square pattern, which is made up of the earthen wall and Brick-encased soil gates, which connected to the earthen Great Wall on the west side. Due to the changes of the times and the influence of natural and human factors, the earthen sites of Liugou Ancient Castle have been damaged to varying degrees, and the conservation and restoration work needs to be entirely carried out. Firstly, this research analysed and summarized the types and conservation status of earthen sites from field investigation results. Secondly, the samples of deteriorations faced by earthen sites and their forming factors are analysed in detail. Finally, based on the principle of “minimum intervention and identifiable”, the research puts forward a repair strategy and specific operation technology for various deteriorations, to provide a reference for the future practice of earthen sites restoration, display, and utilization of Liugou Ancient Castle.
