Realizing the importance of the site, the Fine Arts Department initiated the renovation of Prasart Muang Sing in 1974. The site then was a mound covered with heavily overgrown vegetation. When the renovation work of the monument was completed covering an area of around 640 rai of land, Muang Sing Historical Park had the official opening presided over by H.R.H. Princess Mahachakri Sirindhorn on April 3, 1987.
