The Military Temple at Hongje-sa was planned as an open space where not only Buddhists but also any citizen can come to enjoy the teachings of Buddha (불음, 佛音), with a focus on realizing social value.

​

 The design concept is based on "Indra's Net" (因陀羅網), which represents the idea that all beings in this world are interconnected without causing obstacles to one another.

​

 The temple breaks away from traditional Buddhist art forms by utilizing creative sculptures and modernized forms and materials, thereby maximizing the sacredness of Buddhism while creating a new and innovative space.

​

 The ceiling of the temple is adorned with Suok lanterns, which have been laser-engraved with Buddhist teachings. Although small in size, these lanterns come together to illuminate the temple as lights of wishes. Additionally, the temple's walls are made with copper plates and decorated with cloisonné, a technique where vitreous enamel is fused onto metal at high temperatures to create vibrant colors. This method represents the seven treasures mentioned in the Amitabha Sutra—gold, silver, lapis lazuli, crystal, agate, coral, and amber. The suggestion to use cloisonné was inspired by the Diamond Sutra's teaching that filling the three thousand great thousand worlds with these treasures as an offering to the Buddha would bring great merit.

 Moreover, as the wall behind the Buddha statue opens, the panoramic view of Gyeryongsan Mountain is revealed, creating a visual harmony between the interior and the natural surroundings.
