With its rich history dated back to the previous century, Phyathai Palace was once known as King Rama V’s place for relaxing and sometimes served as the royal cottage for the King’s agricultural experiments. The Queen Mother and King Rama VI once spent their times at the Palace. It was later transformed into a five-star hotel and the Royal Thai Army’s medical headquarters, which marked the beginning of Phramongkutklao Hospital. Phyathai Palace now serves as a museum with these interesting sections:

Pimarn Chakri Throne Hall

The central building of the throne halls, the two-storey-structure is a combination of Romanesque and Gothic architecture decorated with impressive fresco-secco paitings on the building’s ceiling and decorative cornice in beautiful flowers patterns. Inspired by Victorian Art, the main door is carved from gilded wood with the King Rama VI’s initial name engraved above.

Waikoon Theppayasatharn Throne Hall 

Located on the east side of Pimarn Chakri Throne Hall, the Romanesque-influenced building was formerly constructed as a two-storey brick-and-cement structure. The third floor was later annexed to serve as the royal bedroom.

Sri Sutthaniwart Throne Hall 

The two-storey throne hall is located on the east side of Pimarn Chakri Throne Hall. Inspired by English Gothic art, the building features an interior small dome. It is connected to Pimarn Chakri Hall by a walkway on the second floor which serves as the reception zone for royal personages. Sri Sutthaniwart Throne Hall boasts a rich, decorative Art Nouveau-inspired flower painting on its cornice and ceiling. In the main room, a Western style-painting of a man, a woman and a sheep is the center of attraction.

Thewarat Sapharom Throne Hall 

Formerly used as the throne room during the time of Queen Saovabha Pongsri, Thewarat Sapharom Throne Hall was influenced by Byzantine architecture with wood structure and center dome supported by arch roofs on all four sides. The Throne Hall’s walls are decorated with paintings of human and flora.

Udom Wanabhorn Throne Hall

This simple, two-storey building does not feature any fresco-secco painting on ceiling and wall. Instead, white ceramic is the main decoration here in which it is placed around the entrance door and at the center of the major staircase. Made from cast steel, the pattern of the handrail is done in Art Nouveau style, with another staircase constructed from cast steel as well. The rooms on the upper share the same planning on both sides while a spacious hall reigns downstairs. A connected walkway was later added to the second floor.  

Mekkala Rujee Palace 

The two-storey teak-wooden cottage features Terra-cotta tiled roof. Inside, the highlights of the Palace are the exquisite color paintings of birds and the royal basin, a bathtub for King after having a haircut.

Royal Concourse 

Featuring Neo-Classic architecture, this area was added after the complete construction of Phyathai Palace. The building is located in front of Pimarn Chakri Throne Hall and used to serve as the concourse for the King’s vehicle and waiting area for those who wished to be in attendance of King Rama VI.

Roman Garden 

Following geometric landscape architecture, Roman Garden comprises a set of garden gazebos as inspired by Roman architecture. In the garden, the gazebo with its dome roof supported by Corinthian Orders is located as the center piece and embraced with roof-free square gazebos on all sides The square gazebos are measured in the same way as the domed pavilion by using orders to support their entablature. Marble statues are featured as decoration in reminiscence of Roman Art. The stairway, which connects to the garden's entrance area with the big pond, is located in the same alignment as the dome and comes with a wide walkway connected with the gazabo. On certain occasions, this gazebo would be used as outdoors stage.
