Bridge - A stone road dating back to the 14th century has been discovered at the remains of the Ho citadel complex in the central province of Thanh Hoa, Veitnam.

The 2km road linking the citadel"s southern gate with the Nam Giao worship platform has been described as the "most beautiful old stone road ever built in the country".

Archaeologists excavated a total area of 1,500sq.m in front of the southern gate revealing blue stones as big as 1sq.m buried up to 1m below the surface.

The road is thought to have been used by the king and the royal family when travelling between the citadel and nearby Nam Giao worship platform to pray to heaven for peace and prosperity at the peak of Don Son Mountain.

Archaeologists have found the road mainly intact and discovered various antiques including metal spears, stone cannon balls and ceramic objects from the early period of the late Ledynasty (1428-1527)

The road has been listed in the heritage file of the citadel to submit to UNESCO by the International Council on Monuments and Sites, a professional association that works to conserve and protect sites of cultural heritage around the world. The association hoped the road would be listed among the oldest stone paths of royal citadels in Southeast Asia.

Archaeologists also hoped to unearth remnants of a bridge at the southern gate that is mentioned in various historical sources.
