Pha That Luang was destroyed by the Thai invasion in 1828, which left it heavily damaged and abandoned. It was not until 1900 that the French restored to its original design based on the detailed drawings from 1867 by the French architect and explorer Louis Delaporte.[1] However the first attempt to restore it was unsuccessful and it had to be redesigned and then reconstructed in the 1930s.[3] During the Franco-Thai War, Pha That Luang was heavily damaged during a Thai air raid.
