2) The archaeological survey
The results of the archaeological survey found artifacts such
as pieces of human skeletons, elephant bones, domestically produced
potteries, Chinese potteries and roof tiles throughout the area.
3) The archaeological excavation in the AREA 1
The archaeological excavation for 6 pits (TP.5-10) found
important evidences within the TP.9 located at the platform of the train
station building at the level of 140-160 cm.dt. (or lower than the current
ground surface of 100-120 cm). Most of the floor of broken bricks and
artifacts were similar to artifacts found in other soil layers. Within the
TP.10 located at near area, rows of wood sticks were found at the level
of 140-160 cm.dt (or lower than the current ground surface at 100-120
cm) and pieces of roof tiles were found in this area, and most,compared to roof tiles found in other soil layers. Therefore, it could be concluded
that the level that was lower than the current ground surface of 100-120
cm should be the original cultural soil layer before the Thonburi train
station was constructed in the reign of King RamaV. They might be the
soil layers from the Ayutthaya or beginning of the Rattanaksin periods.
