The cathedral church of the diocese is Holy Trinity Cathedral,
Wangaratta. The land on which the church is built was donated to the parish by William Henry Clark, a pioneer of Wangaratta. The
foundation stone was laid in 1908 by Bishop
Arthur Green, the
Bishop of Ballarat, and was dedicated on 24 August 1909. A second section was built between 1922 and 1924. The building was faced in locally quarried
granite to a design by the
English architect Walter Butler. The baptistery, designed by the church architect
Louis Williams, was completed in 1965. The cathedral houses eight
change ringing bells. Cast in 1806 by
John Rudhall, they are the oldest "complete" ring of bells in
Australia. They were originally housed in
St. George's Church, Bolton, and were first rung in 1987 once a tower had been built to house them. The current
organ was built in 1902 by
Henry Willis & Sons and is the fourth instrument to be housed in the cathedral. ==Deans of Holy Trinity, Wangaratta==
