It was Princess Grace who had this garden designed. It is an oasis of green. Here, everything is symbolic. Some of the arrangements follow Shintoïstes ideals. Case in point is thearched bridge which is red to represent happiness and which takes you to the islands which represent the Gods. Others draw inspiration from buddism such as thezen garden , the sea of gravel which is raked into an ellipse, to reflect perpetual motion. The minerals include porphyric rock, gravel, and granite.
