More than 200 other houses were damaged, and numerous buildings of historical significance were lost, including the Mount Franklin Chalet, which was built in 1937–38 for the Canberra Alpine Club and was the first club-built ski lodge in mainland Australia, and many others in the Namadgi National Park. Nil Desperandum and Rock Valley Homestead, the two historic houses at Tidbinbilla, were destroyed. Most buildings of the Mount Stromlo Observatory, operated by the Australian National University, were destroyed, including the observatory's Oddie telescope and its dome, which had been built in 1911 and was the first federal building in the ACT.
