The National Carillon is a large carillon situated on Queen Elizabeth II Island in Lake Burley Griffin, central Canberra, in the Australian Capital Territory, Australia. The carillon is managed and maintained by the National Capital Authority on behalf of the Commonwealth of Australia. It has 57 bells, ranging nearly 5 octaves from the bass bell in F# to the treble bell in D. History The carillon was a gift from the British government to the people of Australia to commemorate the 50th anniversary of the national capital, Canberra. The structure was the subject of a limited competition between three selected Australian architects and three selected British architects. Assessors of the competition were Lord Holford, Sir Donald Gibson and Sir John Overall (Chairman of the National Capital Development Commission). The winners were the Western Australian firm of Cameron Chisholm Nicol. The carillon was designed in 1967, built during 1969 and completed in 1970. The three columns of the design symbolise the British and Australian governments and the City of Canberra. Queen Elizabeth II officially opened the National Carillon on 26 April 1970. The carillon has a symbolic value in the link between Britain and Australia. It also has some historic value for its association with the commemoration of the 50th jubilee of the founding of Canberra. The tower stands tall. The concept was developed in 1968 by Don Ho, an architect at Cameron Chisholm Nicol. The carillon bells and mechanism were designed and constructed by John Taylor & Co of Loughborough, England. The carillon is a good example of the late twentieth century Brutalist style. Its use of strong shapes which are boldly composed, the diagonal line of the roofs, large areas of blank wall, use of precast non load-bearing wall panels and strongly vertical windows and openings are all features of this style. 2019 upgrade In 2019, the carillon was upgraded with a new clavier, a fully replaced transmission and the addition of 2 new bells to add the lowest semitone and a new highest bell. The new lowest semitone bell was called the Ngunnawal bell, in recognition of the first peoples of the Canberra region. This bell weighs just over 5 tonnes and sounds the note G. The other bell added was a new lightest bell to extend the rage of the instrument to nearly 5 octaves. This work was carried out by John Taylor & Co. The work
