One of the attractions of Zhemgang is the Trong Heritage Village, an array of traditional stone masonry houses built on a hillock overlooking the imposing Zhemgang Dzong/Fortress. The neatly laid down stones, skillful use of locally available materials, earthquake resistant techniques, cobbled pathways and natural airflow and lights of the entire village exemplifies the architectural splendor of Bhutan well maintained over the centuries. The clustered two storied traditional stone houses with wooden windows makes Trong heritage village distinctive.

It was the initiative of the 4th King Jigme Singye Wangchuck and people of the community to preserve this unique Bhutanese architecture and promote eco-tourism in the area.

Not much is documented or written about the origin of the village however according to oral sources, Lam Zhang from Kheng Gongphu is believed to have been assassinated there and therefore the place came to be known as Trong (an honorific term for assassination).
