ABSTRACT
New forms of popular culture offered by globalisation often leave out traditional art. As a result, the nation's supportive community began to gradually abandon the native culture. The traditional theatre of mendu in West Kalimantan is one of the regional arts that "lives reluctantly dead do not want to." Artists and community leaders in West Kalimantan's Sungai Duri 1 area, Mempawah regency, founded the Tirai Budayaart gallery in response to these concerns. This gallery's mission is to protect and promote its distinctive culture. For example, it invites newcomers to take part in mendu's historic theatre revival. The study's goal is to shed light on the gallery's role in preserving West Kalimantan's traditional theatre, TiraiBudaya. It is a case study approach that employs a descriptive qualitative methodology. Afterward, a description of the function of the TiraiBudayaart gallery in preserving the traditional mendu theatre as a hereditary heritage and a West Kalimantan cultural treasure was produced as a result of the study's findings.
