The mountainous region of Yen Tu has been a ventre of Buddhism for many centuries and is the starting point of the Buddhist sect of Truc Lam.
In the wide ensemble of vestiges in Yen Tu, there are 11 pagodas and close to 100 shrines and towers.

Yen Tu festivities begin on the ninth day of the 1st lunar month and last until the end of the 3rd month. One form of entertainment is to climb the peak to where the Dong pagoda was built. On the way you'll see pagodas, a tower, a tream and a farest.

At the top, after having burned joss-sticks, you will seem to be lost in nature somewhere between the sky and the earth. When clear you can perceive almost all of the north-east area from here.
There is a popular saying about Yen Tu : "Even after 100 years of virtuous religious life, if you don't come to Yen Tu you can not be called a true religious persons".
