Conny Waters – AncientPages.com – It typically occurs that beneath fashionable cities and streets, archaeologists unearth the traditional remnants of a whole settlement of which existence was beforehand unknown to researchers.
Prof. Dr. Santi Pailoplee from the Division of Geology, College of Science, Chulalongkorn College
Now, a workforce of researchers on the Division of Geology, College of Science, Chulalongkorn College, led by Prof. Dr. Santi Pailoplee discovered proof of an historic earthen embankment surrounding the previous metropolis of Nakhon Ratchasima, situated in Muang District, Nakhon Ratchasima Province.
These remnants counsel that historic communities could have existed previous to the development of the previous moat in Nakhon Ratchasima. This improvement occurred in the course of the reign of King Narai the Nice within the Ayutthaya interval, which spanned from B.E. 2199 to 2231.
This discovery stems from the evaluation of aerial pictures captured in 1954 by the Royal Thai Survey Division. Prof. Dr. Santi’s analysis revealed that, geographically, the area across the previous metropolis of Nakhon Ratchasima was as soon as a floodplain related to the Previous Takhong Canal. This canal originates from Lam Takhong within the west and traverses by way of the northern part of what’s now a densely populated metropolis moat space.

In an evaluation of aerial pictures from 1954, Prof. Dr. Santi recognized what appeared to be an earthen embankment extending in a straight line to the north, west, and east of the Previous Takhong Canal. This commentary led to the speculation that this embankment may mark the boundary of one other historic group situated north of Nakhon Ratchasima’s previous metropolis, which was distinctly enclosed by a sq. moat.
The world surrounding the previous metropolis of Nakhon Ratchasima has undergone appreciable adjustments because of fashionable city actions. Nonetheless, an evaluation of what are considered historic earthen embankments, together with the stream patterns of the Previous Takhong Canal, reveals that these don’t align with pure water motion. Two geographical anomalies function indicators:
1. In the course of the flood season, when water lots from the Previous Lam Takhong strategy from the west and encounter the earthen embankment on its western aspect (now often called Soi Prapa Street), this embankment obstructs the stream, leading to flooding exterior its boundaries. Subsequently, as water step by step passes by way of slim drainage channels left inside the embankment, important erosion happens in these exterior channels.
This course of transports sediments extra extensively than in different areas, finally forming lowlands that later advanced into ponds or swamps located earlier than the embankment (presently acknowledged as Assadang Reservoir).

2. The substantial quantity of water retained exterior the embankment is compelled by the construction to stream behind it at constantly elevated velocities. Consequently, when the Previous Lam Takhong enters the area behind the embankment, which encompasses an historic group space, it undergoes important horizontal erosion. This phenomenon leads to a stream that’s extra sinuous than regular, exhibiting higher winding than typical streams.
The reason for this elevated meandering lies within the focus of a giant quantity of water that ought to ideally disperse evenly throughout your complete space however is as an alternative confined exterior the embankment and compelled to traverse solely by way of the Previous Lam Takhong channel.

Irregular stream conduct attributable to earthen embankments is a notable function in a number of historic group areas inside Thailand’s Northeastern area. This phenomenon might be noticed in locations like the traditional communities of Khok Kham and Khok Sung in Buriram Province, the traditional group of Pho Si in Sakon Nakhon Province, and the traditional metropolis of Phlapphla. Moreover, it has been recognized on the northern earthen embankment of the previous metropolis of Nakhon Ratchasima throughout this survey.
Primarily based on the proof of those two irregular stream conduct patterns, it may be interpreted that the sq. boundary seen within the 1954 aerial pictures is an earthen embankment that marked the residential boundaries of an historic group, much like these present in different areas talked about above.
The survey exhibits the earthen embankment lined an oblong space with a 2-kilometer northern embankment. The western and japanese embankments’ lengths could not be initially assessed because of overlap with the Nakhon Ratchasima metropolis moat.
An evaluation of embankment development patterns in historic communities exhibits that streams typically flowed by way of the group heart.
Upon measuring the space from the northern embankment to the Previous Takhong Canal, it was decided to be 850 meters. Extending this space southward by a further 850 meters from the Previous Takhong Canal would lead to alignment with an present construction, Chompol Street, which serves because the principal thoroughfare traversing the middle of Nakhon Ratchasima’s historic metropolis.
Professor Dr. Santi Pailoplee posits that Chompol Street could have served because the southern boundary of an historic group. He preliminarily infers that this group was established previous to the founding of the previous metropolis of Nakhon Ratchasima. Based on his evaluation, “the unique southern embankment might need been repurposed from its preliminary function as a group boundary marker to operate as the primary central highway in previous Nakhon Ratchasima.”
Primarily based on the preliminary speculation that the southern boundary is Chompol Street, it may be concluded that the form of this historic group was one thing near a sq.. This helps help one other perspective that this earthen embankment isn’t a baray (a big water reservoir in historic Khmer tradition), which was usually rectangular in form with a width:size ratio of roughly 1:2 in nearly all circumstances.
By measuring the world’s dimensions, 2 km extensive by 1. 7 km lengthy, we discover it covers 3. 4 sq. kilometers or 2, 125 rai. This group is twice the scale of the previous metropolis of Nakhon Ratchasima and bigger than different talked about historic communities.
Prof. Dr. Santi Pailoplee said that this preliminary examine, based mostly on distant sensing knowledge, wants additional archaeological surveys to confirm its accuracy. He hopes these findings will information future analysis and encourage delight in Nakhon Ratchasima’s wealthy historical past.
