The Ruined Vihara of the South Gate 
This laterite ruined base of a ‘Vihara’ (The ruined No.223), the Buddhist assembly hall, is located near the south gate and outside the town wall of Si Mahosot. It is conjectured that between the 7th and 12th centuries CE the assembly hall (12.60 x 16.25 metres) with large and high pillars supporting the roof enshrined a stone standing image of Buddha preaching and a Dharmacakra (Wheel of the Law), and a plain rectangular seat, built on the left of the image, for monks to perform a ritual or preaching. On the lower platform a cloister was provided for urban and rural Buddhists to participate in a ceremony of circling the vihara, as a tradition of the Buddhists of the Dvaravati town.
