One banner depicts the bell tower of St Michael and All Angels Church, which was designed by pre-eminent Gothic Revival architect Benjamin Mountfort and constructed from 1860-1861.

This year is the 150th anniversary year of the founding of the "Mother Church" of the Canterbury settlement. The erection of the banners coincided with Heritage Week and St Michael and All Angels presented a programme of events highlighting history and heritage.

The other banners also illustrate elements of the Gothic Revival style of architecture that characterises Christchurch.

Two of the banners depict elements from the Christchurch Arts Centre — the Clock Tower block, also designed by Mountfort in the 1870s, and the cloisters of the North and South quads that Samuel Hurst Seager designed.

The fourth banner shows the decoration using different coloured stone on one of the lancet-arched windows at the Canterbury Museum that is another Mountfort creation.
