Long Sơn Communal Heritage

Long Sơn Communal Heritage centres on Nhà Lớn Long Sơn and the enduring Ông Trần tradition, linking worship, shared institutions and community memory.

Long Sơn offers a rare integrated example of community organisation, worship and material architecture, rather than a monument isolated from living practice.
Overview

Understand the place through history, meaning, architecture and surviving evidence.

On Long Sơn island, Nhà Lớn is more than a single shrine. Its complex of worship halls, communal buildings and memorial spaces reflects the settlement and ethical teachings associated with Ông Trần, born Lê Văn Mưu. The buildings preserve a distinctive wooden architectural environment, while ceremonies and community practices give the site a living role. Nhà Lớn was recognised as a Vietnamese national historical-cultural relic in 1991; this is not UNESCO World Heritage inscription.
