This is a group of four large stupas, each 42 metres high. These four chedis are dedicated to first four Chakri kings . The first, in green mosaic tiles, was constructed by Rama I to house the remnants of the great Buddha from Ayuthaya, which was scorched to remove its gold covering by the Burmese. Two more were built by Rama III, one in a white tiles to hold the ashes of his father Rama II, another in yellow for himself. A fourth in blue was built by Rama IV who then enclosed the four chedis leaving no space for more to be built.
