It is hard to imagine, in the middle of Hanoi capital, inside a mountain rise in the middle of the delta, there is a bone tank and “bone stream” contains 3,600 sets of the skeleton.

Visiting the pagoda Thay, tourists of Vietnam package Tours cannot ignore Cac Co Cave (also known as Than Quang Cave). This is not only the highest cave of Sai Son Mountain, Quoc Oai, Hanoi, but also attracts visitors by the mystical color covered thousands of years.

Deciphering “tank of bones” in Cac Co Cave

Passing over 200 stone steps, up to the top of the pagoda, through a gentle but slippery slope, visitors will come to the cave entrance. Deep, dark, you must use a flashlight and fumbling step by step to be down. Going through the stairs upright, lingering stones, you will see the body of the remains. The large basin was built of stone, with a small altar in front. Pointing the torch carefully, protruding your head through the square hole, you will feel chilled to the rush: in the tank, there are many skulls with bones of forearms, legs and countless pieces of bone, broken skulls with yellow, black. There are also is real money, paper money, rubbish …

The story is that this place is a giant tomb of Lu’s army, the anti-Han period, more than 2,000 years ago. But then, the war failed, the army of this dynasty retired into the cave on Mount Sai Son. The enemy did not pursue, carrying large boulders that covered the mouth of the cave, killing thousands of soldiers in the mountains.

Over 2,000 years later, in 1933, the people of temple together with the Buddhist and Sai Son people broke through the gates, built a large tank, then proceeded to gather the bones throughout the cave poured into the tank.

The mysterious hell

Cac Co Cave is located near the top of the main mountain, visitors want to visit the right through a steep rocky steep path. According to an old person selling water for more than 30 years here, the cave is a place to pray for love, happiness, richness.

The way down to the cave is slopping even though it was built with cement and iron bars to hold. In the cave, darkness almost covers, but light ray down through the gates on sunny days glistening on stalactites shine a mysterious light. On rainy days, the humid air in the cave covers with a dense fog full.

It is said that the cave has nine floors, corresponding to nine floors of hell. In there, the bones of Lu Family and the altar are on the third floor. At the entrance, there is a deep cave, which is the way down to the fourth floor according to tour guide of Hanoi City Tour. In the darkness, if you try throwing a stone, more than a minute later, there is echo like thousands of unhappy soul. Tour guides said that someone was tying rope belly down to explorer but down about 30m, they cannot see the bottom and feel only dark and stuffy so they went back.

Following the slippery slopes, we arrived at the Lu Gia altar, where the ancient anti-Han loyalists had died. The air smells of incense smoke make people feel cold. Going deeper is a mysterious giant bone tank.
