Buried around 50–70 centimeters beneath the ground, the round shot,which were carefully polished, have diameters ranging from 5-8centimeters. Most of them were made from limestone, while the rest werefrom pebble and sandstone.
Ammunition similar to these interms of materials, shapes, sizes and technique was once excavated atthe Ho Dynasty Citadel. A theory believes that all of them, as popularmilitary equipment during the reign of Ho Quy Ly (1398-1407), were usedfor cannons invented by Ho Nguyen Trung, the King’s first son.
Local people today still tell folk tales about the Ho era’s army base.
The findings are expected to provide important grounds forresearchers when it comes to the issues of history and militaryactivities of the Ho dynasty in the national history.
The HoDynasty Citadel, located on the two communes of Vinh Tien and Vinh Long,Vinh Loc district, Thanh Hoa province, is a unique stone-madearchitectural work in Vietnam.
Built by Ho Quy Ly in1397, the citadel was Vietnam’s capital at that time, which was famousfor being strategically located and easily defended. It was protected bya mountain range to the north, while the Ma River runs to its west andthe Buoi River to its south, creating a huge natural moat.
For more than 600 years of existence, most of the buildings inside theCitadel were destroyed. The traces of the foundations supporting the oldpalaces still lie hidden under the rice fields.
On June 27, 2011, the Citadel was recognised as a World Heritage Site.-VNA
