The former palace built by King Rama VI to stay and look out over the farms, plantations, and livestock in the area.
After his death, his brother King Rama VII ordered the palace be converted into an international hotel.
This luxury hotel could welcome only 40 guests. The rate per night varied from 10 baht to 120 baht. Sadly, due to the gradual loss of the business, the hotel ended seven years later.
Phya Thai Palace then became the site of the first Thai radio broadcast station. Later, after a change of government, the Palace became a clinic for the Royal Thai Army and has since changed its name to the Phramongkutklao Hospital.
