[2][3] The church was consecrated in memory of Mary Elizabeth McGoun (died 1867), wife of Col. Thomas McGoun of the 6th Madras Native Infantry (died 19 April 1868 at Marseilles on the way back to Scotland, has a memorial stone at the St. Andrew's Kirk, Madras), it was once known as the martyr's church.

[9] As a result of the declining Scottish members, in order to attract more people to the church, Kannada services were started in 1965.

[4] The church building has the Gothic structure, with a height of 43 ft., length of 105 ft., and width of 57 ft. Stained glass covers all the windows and the large gable.

The pulpit is made of teak wood, and is richly carved, in sync with the church architecture.

[4] St Andrew's Kirk was the second church to be designed by Richard Hieram Sankey, (an Irishman from County Tipperary), after the Anglican Cathedral of All Saints at Nagpur.

[11] Architecturally, St. Andrew's Church has many similarities with the main block of the Central College, Bangalore, with its Gothic style, characterised by steeping roof of Mangalore tiles, a row of decorative ridge-tiles on the top, turreted parapets and gables, iron crested towers, intricately done plaster motifs, railings of cast iron, and pilasters and pavilions rising from the wing.

[12] Sankey published as description of St. Andrew's Kirk at Bangalore in the journal, Professional Papers on Indian Engineering.

The tower was originally intended to be a steeple has a height of 90 ft., nave to the wall plates under the roof trusses was 34 ft., and the side aisles were 23 ft. Brickwork, plastering and chunam (lime) was used in the construction.

[10] There is a 25 ft. stained glass above the altar, fusing 15 panels into one, created by Scottish artist Alex Ballantine and his assistant Gardiner, in order to commemorate the diamond jubilee of the reign of Queen Victoria in 1897.

At the base, the Old Testament characters of Abraham, Moses, King David and Prophet Isaiah are painted.

The Bishop constituted a Church Renovation Implementation Committee, taking advice from the professors of Structural Engineering from the Indian Institute of Science.

Restoration work was undertaken, and the completed just in time for the church to celebrate its 142 years on 26 November 2006.

In order to commemorate the restoration, on 4 January 2009, eminent organist and music laureate Prof. Dr. Richard Marlow, Director of Music, Trinity College, UK was invited to perform and organ recital, during the re-dedication of the church organ ceremony.

[1][7] There existed a St. Andrew's High School, as per the Report on Public Instruction in Mysore, for the Year 1877–78, and other records.

The school was meant for the poorer sections of society and when it started, there were 50 children from poor families, who received free education, uniform and mid-day meal.

In 1977, the church, re-established the St. Andrews's Primary School at the Siddapura Slum, for the benefit of under-privileged children.
