This Great Bodhi Tree is a historical tree personally planted by His Majesty King Chulalongkorn (Rama V) at this sacred site. The King brought the sapling from the original Bodhi Tree in Bodh Gaya, India, to be enshrined at this island temple. The act of planting this royal tree reflects his profound faith in Buddhism and the close bond he shared with the people of Lopburi. Today, the Bodhi Tree has grown vast, offering shade and serving as a spiritual anchor for locals who come to seek blessings. It stands as a priceless natural and historical heritage, confirming the strong relationship between the monarchy and Wat Mani Cholakhan.
