Swan Bells, Bell tower at Barrack Square, Perth, Australia

Swan Bells is an 82.5-metre copper and glass campanile at Barrack Square, its concrete bell chamber wrapped in 30-metre copper sails and a glass spire whose horizontal spokes narrow toward a point. The six-storey chamber, cast in reinforced concrete, holds 18 bells weighing about 9 tonnes. Soundproof louvres and doors direct the ringing toward the city or the Swan River.

The twelve St Martin-in-the-Fields bells date from before the 14th century and were recast under Queen Elizabeth I and by the Rudhall family between 1725 and 1770. In 1988 they were donated to Western Australia for the bicentenary, on the initiative of bellringer Laith Reynolds, and six new bells were later cast at Whitechapel. The tower opened on 10 December 2000.

The bells are change-ringing bells, rung in the English full-circle method; the set forms a sixteen-bell peal with two extra chromatic notes. Twelve came from St Martin-in-the-Fields and are among the few sets of royal bells, the only known set to have left England. They rang as James Cook set sail on the voyage that reached Australia.

The tower stands at Barrack Square on the Swan River foreshore, reached by walking and cycling paths; the surrounding precinct has cafes, shops and reflection pools. Soundproof louvres and doors can direct the bells' sound toward the city or the river. The six-storey bell chamber is reinforced concrete cast in situ, designed by Arup, and the glass spire's spokes radiate from a central axle.

The Great ANZAC Bell, cast in 2018 by VEEM Limited of Canning Vale to mark the centenary of the 11 November 1918 armistice, weighs 6.5 tonnes. Unlike the 18 change-ringing bells, it is swung by an electric motor supplied by a Belgian firm.
