Worshippers will see how New Zealand's historic Christchurch Cathedral looked before it was partially destroyed during a benefit concert at its Scottish "twin" on Monday night.
St Mary's Episcopal Cathedral in Glasgow is an almost exact twin of Christchurch Cathedral.
The damaged cathedral was described by its dean Peter Beck as "the heart of the city", adding that its heart had been "broken" by last week's 6.3-magnitude earthquake that killed at least 147 people.
Glasgow's St Mary's was built at the same time to a design by the same architect.
Scottish singers are coming together tonight at St Mary's, on Great Western Road, for a benefit concert for the people of Christchurch. The concert will also feature the music of several New Zealanders living in Scotland.
Cathedral Provost The Very Rev Kelvin Holdsworth said: "People in Scotland have all kinds of strong links with people in New Zealand.
"This concert is an act of solidarity with the people of Christchurch.
