Bangkok's Grand Palace and the temple complex of Wat Phra Kaew belong to some of the most remarkable building complexes in the world. They were founded by King Rama I in 1782 when Bangkok became the new capital of the country. There is one shared entrance to the two sights. Many of the buildings inside the temple area a bear resemblance to earlier Ayutthaya buildings. The great , golden chedi Phra Si Ratana contains a piece of bone of the Buddha, and the particularly beautifully ornamented chedi next to Phra Mondhop is a library of scriptures. The two biggest buildings are the Bot and the Pantheon. The Bot houses the most sacred statue in Thailand-The Emerald Buddha ,which is 66 centimeters tall, cut from one single piece of jade and resting on the platform 11 meters above the floor. The statue is thought to be from the 15th century. At the time, is was placed in Chiang Rai in northern Thailand. On its way to Bangkok , the statue has been in Lampang, Chiang Mai and Vientiane. At the beginning of each of the three Thai seasons ( summer ,rainy and winter season) , the King changes the clothes of the Buddha at a grest ceremony. Originally , the Pantheon should have housed the Emerald Buddha. Gigures of Chakki Kings are now display here.
