Three archangels will be watching over Christchurch this Christmas despite not having a cathedral to reside in.

ChristChurch Cathedral'sl marketing and development manager, Rev Craig Dixon, says he thought of suspending the sculptures of the angels Gabriel, Michael and Raphael above the central city after seeing two idle cranes within the cordon.

He contacted the owner of the crane company, Tim Smith of Smith's Cranes, for help to make his idea reality.

The sculptures, which used to hang inside the cathedral each Christmas, had to be strengthened to withstand the weather.

They represent consolation, comfort and hope.

''They are predominantly made of fibreglass over a steel skeleton, so have a similar construction to small planes," says Caroline Trevella, of Rangiora's Bizzart, who created the sculptures with her daughter Carly.

"We have discussed with aircraft engineers the best way to ensure they can withstand weather elements."

Craig says: "I believe they have a universal appeal. The notion of angels resonates with many people. They are seen as a protective presence.

"These angels, in particular, will also represent powerfully the cathedral's ongoing life in the city and region."

The first angel, Gabriel, is suspended above Worcester St, directly in line with the cathedral.

The second angel will fly over the corner of Hereford St and Oxford Tce, near the City Mall entrance.

The location for the third has yet to be confirmed.
