Ringing takes place before the 9:30 am Sunday service, to mark special occasions, and for weddings. The bells are rung by members of the Australian and New Zealand Association of Bellringers. The bell tower is equipped with sound control and electronic simulator equipment which is utilised for Monday night ringing practice and to aid in the teaching of new ringers. The bells are named after deans and administrators of the cathedral since 1925 when the role was separated from that of the Bishop of Brisbane. Bell names, weights, and pitch are listed as follows: Other buildings Buildings associated with St John's include Webber House, Church House, The Deanery (formerly Adelaide House) and St Martin's House. These buildings provide the traditional experience of only having a full view of the cathedral when quite close (after having wound one's way through narrow medieval city streets) thus adding to the impact and feeling of grandeur. Webber House Webber House was built in 1904. It was designed by Robin Dods (1868–1920). The stone used in the Webber house came from the old St John's Pro-Cathedral in William Street. Webber House was formerly known as School House and housed St John's Primary School until 1941. The school went on to become Anglican Church Grammar School. Church House Church House was built in 1909. Also designed by Robin Dods and was designed to conform to Pearson's concept of St John's Cathedral and its traditional cathedral setting. (The heart design found in many of Dods' buildings can be seen on the iron gates.) Both are Gothic in overall form and design, having details mainly in the style of Art Nouveau. They have been placed to conceal a view of the cathedral from a northerly approach. Adelaide House The oldest building in the precinct is The Deanery, also known as called Adelaide House, built in 1853. From the verandah of this building the first Governor of Queensland, Sir George Bowen, read the proclamation declaring Queensland a separate colony on 10 December 1859. The building then became Queensland's first government house. St Martin's House The other more eclectic building with Gothic touches found in the precinct is St Martin's House, formerly St Martin's Hospital. It was built as a war memorial after the First World War and is dedicated to St Martin of Tours as 11 November (Remembrance Day) is his feast day. Designed by Lang Powell the design
