Bangkok is translated as "the village of the wild plums".  It was reconstructed as a home of the king when Ayutthaya had been overun and ransacked by the Burmese in 1767.  The kinnara are mythical forest figures of Buddhist cosmology.  Here these statues are standing by the doorway of a building called Prasad Phra Tepbidorn which houses the pantheon statues of the first eight kings of the Chakri ruling family.  It  is inside the palace grounds near the Temple of the Emerald Buddha, Wat Pra Keo.  Behind it you can see a small section of one of several Buddhist stupas on the grounds.
