The mystery of ancient “Mac Citadel” in Phu Tho province
In Ba Lam hamlet, Cao Duong commune (Phu Tho province), gates of a mysterious ancient citadel have long been referred to by locals as the “Mac Citadel” – named after the Mac Dynasty, which officially ruled Vietnam for 65 years from 1527 to 1592. To this day, no archaeological evidence has definitively confirmed the date of its construction. Several residential structures built within the citadel’s grounds have gradually eroded the remaining traces of this historical site.
