There was a restoration during the reign of Somdet Phrachao Prasatthong in order to heighten the Prang, but this caused a serious damage to the top and the Prang was left alone with the portico.It was so unfortunate, as it was such an enormous and magnificent one. In 1956 the Fine Arts Department made another attempt to renovate and found a large number of invaluable antiques, such as the stone casket containing the relics.
