In 1232, due to the war with the Mongols, the move of the capital from Kaegyeong to Ganghwa Island was very urgent. From this time until returning to Kaegyeong, Gang-do(江都) became the capital of Goryeo. Gang-do was modeled after Kaegyeong and took on the shape of a capital. Ensuring that life in Kaegyeong could be maintained on Gang-do was the principle that constituted Gang-do, and it was in the same vein that many temples were built. In order for Gang-do to establish its status and function as a capital such as Kaegyeong, Buddhist temple was an essential facility. Important temples of Kaekyung were built on Gang-do, and national Buddhist rituals were also held. Private temples of bureaucrats were also built, and monks traveled between Gang-do and the land to conduct various Buddhist rituals and to manage temples. In addition, the temples on Gang-do reflect the characteristics of the times during the war with the Mongols and the power of the Choi Family’s Military Regime.
