Mittagong Maltings was a three-malthouse complex in the Southern Highlands, built between 1899 and 1916 to supply malt to New South Wales breweries. The Malting Company of New South Wales put up the first malthouse in 1899 between the railway line and Nattai Creek. Tooth and Co bought the operation in 1905 and built two more malthouses, in 1906 and 1916, taking the complex to the imposing scale that still defines the Mittagong skyline. At peak the maltings processed 140,000 bushels of barley a year. Fires damaged Malthouses 1 and 2 in 1942 and gutted Malthouse 3 in 1969, but production continued until 1980. Tooth and Co put the holdings up for sale in 1981. The buildings stood empty for almost forty years until Halcyons Hotels bought the site for $6.05 million in 2019, planning to retain the exteriors and convert the interiors to mixed use.
