VietNamNet Bridge – Under the mossy old gate of the Son Tay Ancient Citadel, embraced by huge roots of 100-year-old trees, a group of teenagers were chatting and laughing and trying to take photos of each other.

 If you follow Highway No. 32 from Hanoi to the west about 45km, you will arrive in Son Tay Town where there exists a 200 year-old citadel built with laterite, a unique construction material.
