THE ROCK GARDEN AT RYOANJI, KYOTO, JAPAN

Although there is debate about when it was created (estimates include the 15th and 16th centuries), Ryoanji is considered one of Japan’s most important Zen dry gardens and has been widely referenced and imitated around the world. Located in a small Buddhist temple complex, the garden is deceptively simple. It consists of 15 rocks, raked gravel, and a smattering of moss set in a 98-by-32-foot rectangular courtyard.
