The Cloister or Vihara Kote of Wat Thewaprasat is a religious architectural structure featuring long, covered walkways that encircle the sacred area. It was constructed to define the boundaries of the Phutthawat zone and surrounds the enshrinement of Phra Phuttha Ketu Mongkhon (Luang Phor To), the largest blessing-posture Buddha image in Phichit Province. Inside the cloister, rows of Buddha images are enshrined along the walkway, allowing devotees to pay respect and perform circumambulation (Wien Thien) around the colossal Luang Phor To in an organized and majestic manner.
