Wat Traphang-Thong-Lang houses a square Mondop which is beautifully decorated by stucco figures in niches. The southern side portrays the Lord Buddha flanked by angels. To the west portrays the Lord Buddha preaching to his father and relatives. The northern side depicts the episode when the Lord Buddha returned to preach to his wife. These stucco figures, especially those on the south side, are masterpieces of Sukhothai art.
