Lying some 40 kilometres from the Hanoi centre, Son Tay Citadel is a unique historical site.
The Son Tay citadel covers an area of 16 hectares. It was built in the French style out of laterite, a material plentiful in the area.
It is a military structure with firing loopholes to protect the gates.
There are four gates leading to the fortress with bridges spanning a moat.
Son Tay Citadel was recognised as a National Architectural Historical Site in 1994.
The People’s Committee of Son Tay Town has planned to open a new pedestrian zone around Son Tay Citadel during the upcoming Reunification Day (April 30) holiday in order to boost tourism.
The 820-metre-long pedestrian zone will span some streets around the citadel to form a space for entertainment, culture and tourism activities.
The pedestrian zone is scheduled to open from 7 pm Saturday until noon on Sunday with contemporary art performances, street music, folk dances, portrait painting, sketching, calligraphy, boat racing, fishing and water puppetry.
