Khao Mo or a replica mountain of Prayurawongsawas Temple is located in the middle of the large pond. It is a rock garden surrounded by a number of miniature chedis and stupas, cathedrals, pavilion, and rare plants. It has been a place of peace and tranquility in the monastery for more than 180 years. The word “Khao Mo” derives from the Khmer word “t’mor” meaning rock.
Thus, Khoa Mo refers to a miniature hill of rocks and stones. There are two types of Khao Mo. One is a small-sized potted Khao Mo, a form of garden arrangement in the same category as bonsai potted plants. The other is a large-sized Khao Mo built on the ground or in the middle of the pond, a structure of rocks and stones piling on top of another to form a miniature hill with coves and nooks.
