Home of the Kings of Siam since 1782, the palace is right in the heart of Bangkok overlooking the river. Considered the spiritual heart of the country as well, the complex of elaborate buildings and temples are still used for ceremonial purposes. Make sure you wear modest clothing and cover your feet before entering! On the palace grounds you will find the Temple of the Emerald Buddha (Wat Phra Kaew), its golden spires reaching toward the heavens and guarded by two giants from the Ramayana epic.
