Map of Si Mahosot ancient town show the location of The Ruined Chariot or Palanquin Building 
The Ruined Chariot or Palanquin Building or the ruined No.16 is located in the north-east area outside the ancient town of Si Mahosot. The remains of two brick walls running parallel, constructed in the middle of the laterite basement of an enclosure, is presumed to have been a place where a chariot or palanquin was kept. Two fragments of terracotta plaque of Dvaravati style, found near a brick wall, is datable to the 11th - 12th centuries CE. The two walls were erected into alignment with the enclosed porch to the north and the opened entrance to the south of the enclosure.

The chariot or palanquin would be likely used to carry an image for a ritual ceremony to and fro between the place and the Buddhist image house, located 160 metres south of the place. Some components of a palanquin or chariot, like bar, hook, and ends of the shaft, have been found from excavations at the image house, dated to the late 12th to 13th centuries CE.
