The Outdoor Exhibition Area features stone relics, such as pagodas, stone lanterns, Buddhist Shrines, and statues, which cannot be easily accommodated in an indoor space. The collection is highlighted by the Bell Pavilion, also known as Bronze of Bosingak Bell Tower, which is classified as Treasure No.2. Most of the displayed works are classified as National Treasures, and the area also functions as a flourishing green space and garden for the Museum.
