The Tuc Dup Hill located in Tri Ton District, belongs to Co To Mountain, An Giang Province. Even though Tuc Dup Hill is only 300m high, it owns an obstacle and dangerous geography with rough cliffs forming caves getting though each other like a bee hive. For these distinctive characteristics together with brave fighting will and wisdom of An Giang people, Tuc Dup became a famous fighting base in the time being against American. During 128 days, the enemy who had a very powerful military force such as fighting jets, artillery and infantry did not defeat our determined fighting will. In the result, American was defeated. Thus, a terrible name was heard �2 million – dollar hill� (the sum of money that American paid for bullets and bombs). Then, peace was set up. The Tuc Dup Hill, which had no trees or phenomena of life because of the war�s impact, becomes vital with trees and becomes a historic site recognised and classified by academic ministry. Being romantic and next to splendid Co To Mountain, Tuc Dup Hill is visited by tourists on special holidays so that they can see the war remains, enjoy fresh air and admire ranging mountains. Visitors can also visit C.6 tunnel, cave for medical ward of military, the youth tunnel and the town hall� It deserves to be an ideal amusing place as visiting people prized.
