Praisaniyakhan

Praisaniyakhan was built in 1871 as the residence of Phra Prichakonlakan (Sam-ang Amattayakun), the former governor of Prachinburi, eastern Siam (former name of Thailand) who was later charged with treason for the corruption over a gold mine in Kabin Buri.

Prince Bhanurangsi Savangwongse was the first director-general of the Post and Telegraph Department and converted the residence of Phra Prichakonlakan to serve as the postal office, naming it "Praisaniyakhan".

In the revolution of 1932, Praisaniyakhan was the first target that the People’s Party (Khana Ratsadon) tried to seize as it was the communication hub handling telegraphy and telephony.

The mission was led by the civil faction of the People’s Party, comprising Khuang Abhaiwongse and Prayoon Pamornmontri.

[3] Praisaniyakhan was demolished in 1982 for the construction of Phra Pok Klao Bridge on the occasion of the 200th-anniversary celebration of Rattanakosin Kingdom (Bangkok).
