A group of experts have suggested several high-tech solutions to help preserve and restore some ancient Cham towers in the UNESCO-recognized My Son Sanctuary, in the central province of Quang Nam, the Vietnam National Administration of Tourism said Thursday on its website.

These solutions are the results of research by a number of universities and research institutes from Moscow and Saint Petersburg, where numerous samples of Cham tower bricks were sent in 2014.

There, experts used X-rays to study the structure and composition of My Son bricks, analyze the minerals and their proportion in the tiles’ composition, and then proposed technological solutions for restoring and preserving Cham towers.

In the future, Russian experts will continue to experiment with more high-tech solutions based on the previous results of research by experts from Vietnam, Japan and Italy on the towers.

The My Son Sanctuary dates from the 4th to 13th centuries, according to the UNESCO World Heritage Center.

It is located in Duy Phu Commune, Duy Xuyen District, Quang Nam Province.

Its tower clusters were constructed over ten consecutive centuries.

The towers of the My Son Sanctuary are the most significant structures of the My Son civilization. They boast a wide variety of architectural designs, and were built of fired brick and decorated with sandstone bas-reliefs which depict Hindu mythology.

Several groups of experts from other countries, such as Poland and Japan, have visited the site to conduct research and look for solutions for preserving the towers and the site as a whole.

My Son was recognized by UNESCO as a World Heritage Site in 1999.
