Phya Tha Kham: The Legend of the Crocodile of Phunphin This tale dates back to a time when the Thapi River was swarming with crocodiles, creatures that instilled fear in the lives of those who depended on the rivers and canals of the past, around 60 years ago. The people of Tha Kham believe that Phya Tha Kham is the guardian who protects good-hearted individuals. Offering prayers and making vows are traditional practices in this town, serving as a source of spiritual refuge that has woven itself into the identity of both the Thapi River and its people through generations.
