Trongsa Dzong was heavily damaged following the 1897 Assam earthquake. It underwent major repair and was restored by both the 1st king, Ugyen Wangchuck and the 2nd king, Jigme Wangchuck in 1927, who renovated the Chenrezig Lhakhang in particular. In 1999, funding from Austria led to extensive restoration works and was reconsecrated in October 2004, coinciding with the enthronement of the Crown Prince.
