A private collector has donated 21 iron swords to Quang Trung Museum in the south-central province of Binh Dinh.

Collector Lam Du Xenh, a member of Quang Ngai province's UNESCO Club, announced the gift on Nov. 23.

The swords, which belonged to the Tay Son insurgent army, are each 3cm wide and 37-54cm long with bronze hilts.

Xenh said he had gathered the relics from An Khe township in the Central Highlands province of Gia Lai, once a strategic base of the army./.
