A set of three old cannons cast in 1821 under the Nguyen Dynasty have been recognised as national treasures.

The cannons, now being preserved at the Ha Tinh Museum, were fished out from a shipwreck in August 2003.

Each of them measures 2.45 metres long and weighs over 1,200 kilograms.

They were carved with dragon patterns and ancient Chinese characters.

The cannons are among the 37 additional national treasures recognised in a Prime Minister’s decision in December 2013.

In October 2012, the Government recognised 30 ancient items as national treasures, which represent Vietnam’s historic regions and eras.-VNA
