The original Knox Church was opened on the corner of Great King and Frederick Streets on 6 May 1860. Soon, a larger church was needed and the present site was bought for £550. The 'new' Knox Church, designed by R A Lawson, architect of First Church, Otago Boys' High School and Larnach Castle, is what you see. It is in 13th century Gothic Style, built of locally quarried bluestone with Oamaru stone facings with a North Otago slate roof. It seats about 900 people. The Church cost £18,383 to build and has been a place of worship since 5 November 1876. The photograph is 21st century. You can compare it to the 19th century painting below.

The front steps are a recent addition linking the church directly to the George Street footpath.

In the Entrance, there are plaques to mark major additions and alterations completed in 2001, and a time capsule.

Two large brasses in memory of the 66 Knox men who died in the First and Second World Wars.

There have been many changes downstairs through the years, most recently a remodelling completed in 1963 to mark the parish's centenary.

A photograph on the wall near the chapel shows the interior 1931-1963.

The present Italian-made chandelier is in the style of the one in the photograph. It weighs 245kg and is held by four wires, each of which can carry 300kg.

The gallery is supported by, 4 cast iron pillars going right up to the roof and 10 wooden ones.
