Chiangsaen, Sukhothai, U-Thong, and Ayutthaya eras, but they were renovated by Rama I and covered with stucco and gold leaves to make them look similar. The Phra Rabiang is intersected by four viharns. The viharn in the east contains an eight metre tall standing Buddha, the Buddha Lokanatha, originally from Ayutthaya. In its antechamber is Buddha Maravichai, sitting under a bodhi tree, originally from Sawankhalok of the late-Sukhothai period. The one on the west has a seated Buddha sheltered by a naga, the Buddha Chinnasri, while the Buddha on the south, the Buddha Chinnaraja, has five disciples seated in front listening to his first sermon. Both Buddhas in the south and west viharns were brought from Sukhothai by Rama I. The Buddha in the north viharn, called Buddha Palilai, was cast in the reign of Rama I. The viharn on the west contains a small museum. Phra Prang - There are four towers, or phra prang, at each corner of the courtyard around the bot. Each of the towers is tiled with marble and contains four Khmer-style statues which are the guardian divinities of the Four Cardinal Points. Phra Maha Chedi Si Rajakarn This is a group of four large stupas, each 42 metres high. These four chedis are dedicated to the 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 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. Viharn Phranorn The viharn or wihan contains the reclining Buddha and was constructed in the reign of Rama III emulating the Ayutthaya style. The interior is decorated with panels of mural. Adjacent to this building is a small raised garden (Missakawan Park) with a Chinese-style pavilion; the centre piece of the garden is a bodhi tree which was propagated from the Jaya Sri Maha Bodhi tree in Sri Lanka that is believed to have originally came from a tree in India where Buddha sat while awaiting enlightenment.
