Archaeologists have discovered the foundations of an ancient palace while working on the Sanam Chai MRT station in Bangkok. The station, located on the Blue Line, is within the city’s historic Rattanakosin Island conservation area. The discovery reveals traces of a much older Bangkok, hidden for generations beneath the modern city. These foundations suggest the presence of a significant palace structure predating the current urban landscape. The find highlights the rich history buried beneath Bangkok and the potential for further discoveries during ongoing infrastructure projects. The MRT expansion is unintentionally revealing layers of the city’s past, offering new insights into Bangkok’s evolution. This discovery underscores the importance of archaeological consideration during large-scale development.
