The ancient Chinese culture of hermitage has had a profound impact on the classical garden art of China, Korea, and other Eastern countries,but existing studies have seldom focused on countries outside of China. This research takes Korea's Dule Garden as a case study, examining the influence of hermit culture on garden space characteristics from multiple dimensions such as the connotation of the name, spatial function, garden site selection,compositional elements, and spatial structure, based on an investigation into Korea's hermit culture and the construction background of Dule Garden. The results show that Dule Garden, in its naming, scenic naming, and functional design, references the hermit garden of Du Le Yuan by Sima Guang from the Song Dynasty, prioritizing locations and environments suitable for hermitage, and considering factors such as Feng Shui. The poetic combination of elements breaks through feudal rituals, creating a cultural atmosphere of Confucian hermitage. The spatial design emphasizes the interior's concealment and connection with the natural world outside.
