19th century -

This, the largest wooden structure in the world, reached the modern age, but the building was in precarious condition. In 1906 a major restoration using modern techniques such as steel framing commenced. The entire structure was disassembled and was not put back together until 1912. Even so there seem to have been difficulties with the work on the roof and on occasion rain leaked into the hall. In 1973 another major restoration began; it lasted seven years and culminated in a ceremony to commemorate the completion of the work in 1980.
