Phra Bowon Ratchawang Si Tha
Phra Bowon Ratchawang Si Tha is in Song Khon Sub-district.King Pinklao had this palace constructed on the western side of the Pa Sa Sak River in Ban Si Tha sub-district in Saraburi in the similar period as when Kina IV had Phra NaraiRatchaiwet constructed in Lopburi. Due to the aim to search for a location for a wartime.King Rama IV commanded King Pinklao (his brother) to conduct an inspection in Nakhon Ratchasima. King Pinklao conducted the construction of his residence in Ban Si Tha Sub-district because from there Khao Khok was easily accessible. King Pinklao, thus, resided at palace throughout his life. The structure of the residence was all made of wood. Some parts were used to construct a palace for his children and others were destroyed and lost. At present time, the location of the palace has been inhabited by the local people. The compound of the residence was very large, covering an area of approximately more than 150 rai. Its lotus base of a wooden house is made of bricks and cement. The base is approximately 20 meters wide and 40 meters long. It is assumed to have been constructed into 2 houses by using very hard bricks (4 inches, thick, 6 inches wide and 12 inch the long). At this time it can hardly be noticed. However, there is an area of around 4 Rai left which the Kamnan-village headman, made of brick and cement with traces of wooden plates on the south of the pond which is called “Bueng Talat Chai” by the locals. It was a gathering site of the ladies of the court when the king took a vacation at this place every year. It has also been told that the king’s ladies were fluent in singing Laotian Songs that he himself was able to play Khaen-a Laotian flute and sing Laotian songs. He also wrote many books of lyrics for Laotian songs, which have been preserved in the National Library until the present time.
