The hill was created during the reign of King Rama III who ordered a large chedi to be build in the Wat Saket temple complex. During the construction however, the chedi collapsed because the soil it was standing on was too soft to support the weight. Years later King Rama IV had the hill reinforced and made higher with large numbers of logs to prevent the soil from sinking any further, and he had a small stupa build on top. The large gilded stupa existing today dates from the reign of King Chulalongkorn (Rama V). In the 1940’s the hill was reinforced again using concrete.
