In 2020, a Heritage Impact Assessment (HIA) was conducted to assess the proposed construction of a new Hall of National Protection (Hogukdaejeon) in Daeheungsa Temple of the World Heritage Property of Sansa, Buddhist Mountain Monasteries in Korea. The HIA evaluated the proposal and how the changes in the spatial composition and the natural setting of the temple could affect the site and its buffer zone.

The assessment focused on identifying potential impacts on the attributes conveying the Outstanding Universal Value (OUV) of the site. The process also looked at the positive impacts of the project highlighting how this could benefit the temple and its communities.

The assessment put forward two recommendations: the need for changes in the building design, and the establishment of mitigation measures for the area of the temple. The HIA provided a base for more informed and better decision making allowing for development to take place without negatively impacting the OUV of the site.
