Wat Si Sithi Karam was established in 1777, originally named "Wat Kaen Lek," but the locals often referred to it as "Wat Nuea." Later, during the time of Phra Si Sithi Karn, who served as the district chief of Manoram, the temple underwent significant restoration. As a result, the name was changed from Wat Kaen Lek to Wat Si Sithi Karam.
