The interior of the main prang features a small, square chamber known as the "Garbhagriha," with a ceiling that tapers upward following the prang's shape. Historically, this space was used to enshrine important Buddha images and store sacred relics within a small stupa or a crypt beneath the floor. The inner walls are constructed from thick laterite and brick to support the immense weight of the layered superstructure above. Although ancient treasures are no longer present due to historical looting, the chamber still offers a sense of mystical solemnity and showcases ancient engineering. Light entering through the single doorway creates a serene atmosphere, highlighting the significance of the sacred objects once housed within.
