Aug 19, Colombo: A project to remove the algae and fungi that had covered the stone ruins of the historical archeological site of Polonnaruwa was launched yesterday.
The project initiated under the direction of the officers at the Chemical Preservation Division of Department of Archeology uses non-chemical methods to remove the algae and fungi covering the stone ruins.
Observations made by the officers of the Department of Archeology have confirmed that a fungus has spread covering the stone ruins including Watadage, carved stone statues, mosaics, moonstone, corawakagala (balustrade), guard stones and stone pillars.
The situation poses a great risk to the existence of the ruins and to their appearance, the Archeology Department says.
According to the Department, the removal of algae and fungi is done carefully using only sand paper and water so as not to damage the ruins in the cleaning process.
