On-site Conservation Activity, Topography and Archaeological Mapping using IT

On-site conservation activities were aimed to prevent the loss of architectural material and damage by water erosion, stop damage by water erosion, conduct archaeological research on the monuments, enhance visibility, and conduct training in the conservation of stone artefacts and in mapping.

The conservation activities were carried out in two areas. The first area to be conserved is the ceremonial road, which was restored under the direction and supervision of the Chief Technical Advisor, Patrizia Zolese.

The ceremonial road is located in the middle of the Vat Phou monuments area, in axis with the main shrine. The ceremonial road is flanked by two tiled galleries, and paved by large stone slabs. Boundary pillars (marker stone) placed every 3 meters on both sides, and a curb of rounded stones (symbolizing the naga or snake) decorates the ceremonial road.

The conservation activities focused on the following:

  • archaeological cleaning of the whole area – 800 sq. m;
  • documentation, levelling and recording of every element found;
  • restoration of about 40 pillars/stone markers that could be re-jointed by glass fibre dowels and epoxy resin;
  • preparation of the new foundation for the pillars; and
  • re-placement of the stone markers in their original locations.

The second conservation activity was the re-mounting of the east pediment of the south quadrangle building, under the supervision of UNESCO Consultant Pierre Pichard. See the Technical Report of Dr. Pierre Richard here.


The conservation activities provided training on the field of two civil engineers and one architect, who are permanent members of the technical staff of the Vat Phou World Heritage Site. Their training included levelling, archaeological and architectural mapping by using total station, handmade drawings and auto CAD restitution. Click here for the graphic documentation.
