Bangkok is a not-so-ancient seat of the Thai Royal court, and you may be passing a surprising and important palace.
The “Celestial Dwelling” forms the main administrative centre of the Thai kingdom. Established by King Chulalongkorn, Dusit Palace was once outside of town and offered space, eventually becoming the primary residence of the kings. Unfortunately, its not visible from the train. But you may be able to see its moat and some of the King’s Royal Guards guarding it.
Chitralada Palace was a residence of the late King Bhumibol Adulyadej (Rama the 9th) – a man with a keen interest in agriculture. He turned the palace grounds is also an operational farm, and its still possible to purchase products under the Chitralada Projects brand. We recommend the famous milk candies, and its honey, which you may be able to find in convenience stores, or at the airport.
