Kim Duc Commune, Viet Tri City, Phu Tho Province
Lai Len Temple is an ancient temple located in Phu Duc village, Kim Duc commune, Viet Tri City.

According to legend, Lai Len Temple is where King Hung taught the Xoan singing style to the people. Lai Len Temple represents a harmonious fusion of a site related to the worship of Hung King and, at the same time, a cultural heritage site related to the origin of the intangible cultural heritage of humanity, Xoan singing in Phu Tho.

Throughout the ups and downs of history, the ancient temple has fallen into ruins.
In 2011, Phu Tho province decided to restore Lai Len Temple on its original foundation, covering an area of nearly 3,000m2, creating a picturesque landscape that has become a tourist attraction for visitors to enjoy the intangible cultural heritage of humanity, Xoan singing in Phu Tho, and the worship of Hung King.

The architecture of Lai Len Temple follows the traditional Dinh-style architecture, consisting of a front temple and a rear temple, facing southeast, with a pointed tiled roof. The Tả Vu and Hữu Vu buildings are constructed in the traditional 5-bay house style. In front of the temple is a solid stone screen with a length of 7.6m, decorated with scroll motifs and mythical beasts.
Within the grand premises of the heritage site, there is a modern Art Exhibition House dedicated to Xoan singing, equipped with all necessary facilities and scientific displays. It is considered a unique museum showcasing Xoan singing in Phu Tho, serving both as an introduction and a performance venue for tourists.
