Sri Prach Sword-Washing Pond, commonly known as the Sword-Washing Pond, is an ancient water source deeply connected to the legendary story of Sri Prach, a celebrated poet during the reign of King Narai the Great of the Ayutthaya Kingdom. According to historical accounts and literary tradition, Sri Prach was exiled to Nakhon Si Thammarat after being accused of an illicit romantic affair within the royal court. Later, he was falsely accused once again by the governor of Nakhon Si Thammarat of violating royal law and was sentenced to death.

The execution is believed to have taken place in an area once known as Pa Kham, which is now the site of Kalyanee Si Thammarat School. Before his death, Sri Prach composed his final quatrain by writing it upon the ground, proclaiming his innocence and calling upon the earth as his witness. The verse ended with a powerful curse, foretelling that the injustice would be avenged by the very sword used in his execution.

The famous lines read in part:
“Let the earth be my witness…
If I am innocent, may this sword return its vengeance.”

Legend holds that the prophecy came true. When King Narai later learned that Sri Prach had been unjustly executed, he ordered the execution of the governor of Nakhon Si Thammarat—using the same sword. After the execution, the executioner is believed to have washed the bloodstained sword in this very pond, giving rise to the name “Sword-Washing Pond.”

In 2009, Her Royal Highness Princess Maha Chakri Sirindhorn graciously presided over the official unveiling of the Sri Prach Monument, ensuring that future generations would remember the life, talent, and moral courage of this great poet, whose legacy continues to shape Thai literature and cultural identity.
