The Clerestory Windows

Above the clerestory and stained windows of the Saints with the different stone tracery design in each window can be seen the Oamaru stone parapets with their succession of arches and designs which makes their way round the front and both walls of the Cathedral. The Oamaru facings in the original white stone must have been very attractive against the Water of the Leith bluestone. The flying buttresses originally made in Oamaru stone blocks by Parker and McNamara to give support to the upper walls had no reinforcing. In 1967 an inspection of the buttresses showed considerable deterioration and that they were in a dangerous condition. The six buttresses on the north and south walls were replaced by Downer and Co. with reinforced concrete. The replacement work took ten weeks.

One of the fourteen clerestory windows, seven in the upper north and seven in the south walls. In keeping with the style of architecture, the windows have highly ornate Oamaru stone tracery in each window is of a different design. Towards the end of 1885 the windows were filed in with cathedral coloured glass and, as well as being tastefully arranged, provide light into the Cathedral. The work was done by Mr David Scott, whose trade advertisement appears in Stones Directory 1886: "Mr David Scott, Leadlight and Church Window Manufacturer. Sign and Ticket Writer. Glass Embosser and General Decorator. Moray Place West, Dunedin."

The Cathedral Building Fund Cash Book shows that over six months Mr Scott received two hundred and seventy-six pounds and twelve shillings for his work on the clerestory windows and the other cathedral glass windows.

In August 1894, due to the deterioration of the lead came binding the glass together, the section together, the seven clerestory windows in the north wall were removed for releading. This work was carried out in the factory of W.A. Raffills and Sons, of Dunedin. The windows, repaired and cleaned of the grime of one hundred years, were replaced in the Cathedral.
