The Phra Achana seated Buddha beyond a narrow opening
Achana means “immovable” or “unchanging” in Pali. A large seated Buddha, about 15 m tall, fills the space enclosed by thick walls. Enter and look up at the serene face while reflecting on the meaning of its name.
From outside you first see the face through the gap in the wall; inside, the Buddha’s body appears along with the thickness of the walls around it. Look first from the entrance, then from up close at the statue. It is interesting to see how the architecture reveals the Buddha image.
A Bodhi grove in the name and thick-walled structure
The name Si Chum is said to derive from a Bodhi grove. The building housing the Buddha image has walls about 3 m thick, with a passage inside the left wall that runs behind the image towards the former roof. It is a structure with a separate path built within the solid outer walls.
The passage is described as having once contained images related to the Buddha. A legend says that someone inside the wall spoke as though the Buddha were speaking, giving the temple the nickname “the temple of the talking Buddha.” Understand this as a legend associated with the architecture.
Visit the open floor area instead of the passage
The passage within the wall is closed to visitors according to the Tourism Authority. Even if you know the old route exists, do not climb inside or try to go behind the Buddha. View the image and building from the areas open to visitors on the ground.
Wat Si Chum is in the historical park’s northern zone. If you have a central-zone ticket, check whether it includes this site before visiting. Even to see one additional Buddha image, you may need separate travel arrangements and admission coverage.
