Quan La Communal House in Xuan La (Tay Ho, Hanoi) has a cave gate leading down to a mysterious large underground cellar with many anecdotes such as the Han tomb's grave, Dan Sa tunnel, and the pit of wealth . .
At Quan La communal house (Xuan La Tay Ho, Hanoi), it is bad at a cave entrance leading to mysterious underground basement .According to Thu from Nguyen Van Luc, no one knows when this underground cave has ever existed.
The underground cave is located underground, more than 4m deep, and has a main gate up behind the Quan La palace harem.The tools in the village made an iron ladder for easy access.Under the cave there are 3 niches, according to the retransmissions, a niche goes to West Lake, a niche goes to Xuan Dinh, a niche goes to the Red River.Each tunnel niche is about 1.5m wide, about 1.6m high.
"All three hatches have been sealed since the Ly Dynasty, so no one dares to break the door deep inside. It is difficult to breathe every day when it is sunny, and the one who stays only 1 minute is right. The points in front of the trees are many, under many solid tunnels, centipedes and rat bugs digging, "said Nguyen Van Luc from Thu.
3 doors with brick arches made of bricks and tiles are printed with beautiful patterns.The first tunnel was about 3m deep, the second tunnel was about 5m long, both were sealed.
Particularly in the winter, it is possible to stand below the cave for a long time without difficulty breathing.
Inside the cave, the bricks are piled with grapefruit, there are many strange patterns.Some places have been damaged, the tiles slipped into the cave floor.
There are many survey teams who have come to know the cave, want to excavate but the villagers disagree because a corner of the cave goes out to West Lake under the harem, if digging can very well affect the old house.
At present, the villagers in the village only look after them, often cleaning up so that mice and snakes do not reside, but there is no underground cave-related activity.Surrounding Quan La communal house, there are 3 thousand-year-old heritage trees such as market trees, banyan tree .
