room, two storerooms, a partitioned manager's office, and a PO box lobby running around the corner under the tower, and filling one and part of another of the breakfronts on their ground floor. Much of the original interior has now been destroyed. The upstairs flat area retains its separate entrance. Heritage listing Charters Towers Post Office was listed on the Australian Commonwealth Heritage List on 8 November 2011 having satisfied the following criteria. Criterion A: Processes Charters Towers Post Office, constructed and extended in the 1890s, is an important regional post office building which has been associated with postal services for over 110 years. Through its scale and late Victorian/Baroque Revival architectural treatment, it is demonstrative of the extraordinary prosperity of Charters Towers, and the associated gold field, in the latter decades of the nineteenth century. The significant components of Charters Towers Post Office include the evolved main postal building and clock tower dating from 1892 to 1898. The additions of 1906-07 are also of significance. Criterion D: Characteristic values Charters Towers Post office is an example of: a post office and telegraph office with quarters (second generation typology 1870-1929) a mixed late Victorian style, early Baroque Revival style with Queen Anne Free Style detailing the work of the Queensland Government architects Alfred Barton Brady, Thomas Pye and possibly also John Smith Murdoch Typologically, Charters Towers Post Office originally combined post and telegraph facilities at ground floor, and residential quarters at first floor level. The clock tower was added in 1898 along with other significant alterations to the building exterior, with further alterations to the rear of the building in 1900. The next phase of alterations in the 1920s or 1930s are believed to have expanded the telephone exchange accommodation, with sheds added to the rear in 1937 to service the telephone network. By the mid 1990s the post office had a remodelled retail area, lunch room, locker room, two storerooms, a partitioned manager's office, and a PO box lobby running around the corner under the tower, and filling one and part of another of the breakfronts on their ground floor. While these alterations changed the internal planning and arrangements, the exterior of the building was not so affected, at least to its 1898 form and detailing. The first floor residential component also remains evident. Stylistically and architecturally, the post office is an important fusion of late Victorian and Baroque
