[1] The Chapel of St Peter's Lutheran College built in 1968, was designed by architect, Dr Karl Langer as the centrepiece of the school grounds, complete with a tree-lined plaza, forecourt, bell tower, and reflecting pool.

It became the home of the Munro family who renamed it Ross Roy and the house and its substantial grounds became a centre of high society life.

Photographs from this time show the grounds immediately surrounding the house to be landscaped and well maintained and the remainder of the property being native growth with a cleared and grassed understorey.

That year a group of German Lutheran and Presbyterian missionaries established Zion Hill (at present day Nundah), a mission for Christianising aborigines, on the outskirts of Moreton Bay Penal Colony.

The school was intended to be a northern adjunct and feeder to Australian Lutheran College#Immanuel Seminary in Adelaide where they would be prepared to serve as pastors and in other ministries.

The congregations of major religions expanded and church attendance and religious society membership rose with accompanying financial improvement.

In the early to mid 1960s a number of the major Christian religions altered the way they ministered to their congregation in order to re-establish themselves within the modern world.

This booklet explored issues related to house design and town planning in a sub-tropical climate and influenced many architects working in the post-WWII era.

Important examples of his architectural work include the Langer residence at St Lucia (1950); Sugar Research Institute at Mackay (1953); St John's Lutheran Church, Bundaberg (1960); Kingaroy Town Hall and Civic Square (1963); Assembly Hall at Ipswich Girls' Grammar School (1964); Main Roads Building at Spring Hill (1966); Lennon's Hotel at Broadbeach (1957); and Lennon's Hotel Toowoomba.

At St Peter's, Dr Langer proposed a fan-shaped chapel with a very tall bell tower and a round concrete reflecting pool behind a paved forecourt at the end of a tree lined plaza.

[1] Langer's design for the Chapel of St Peter's Lutheran College was in a modernist style and typical of his architectural concepts.

Dr Langer integrated native planting into his schemes; at St Peter's he proposed hedges of lemon scented tea trees for the plaza.

In lectures for architecture students at the University of Queensland he referenced the design of St Peter's chapel and its context (the forecourt/plaza and surrounding buildings) as an example of applying the European model of a functional town square to the College campus.

The curved east wall is plain and dominated by the Cross (a symbol of the resurrection), seemingly floating in a strong light symbolising the rising sun.

The foundation stone was laid 17 September 1967 and the chapel was opened and dedicated 14 June 1968 with Dr M Lohe, President General of the Lutheran Church, as guest speaker.

[1] The chapel bell was donated by Pastor Franz Finger who was closely associated with the establishment of St Peter's and in its ongoing ministry and served on the College Council.

[1] At some time, the large sandstone WWII memorial monolith was moved from its earlier position on the northern side of the boys' dormitory to the southern edge of the chapel forecourt.

[1] The Chapel of St Peter's Lutheran College, Indooroopilly, is a fan-shaped building with a bell tower and large concrete paved forecourt terminating a tree-lined plaza.

[1] At the southern end of the front a tall bell tower made of three concrete fins squats over a small round drum of the meditation chapel, attached to the building by a slender covered corridor.

[1] The north and south elevations are yellow face brick and comprise a series of stepped blade walls with west-facing windows.

Secondary entrances to the nave are located along both sides and the low form of the vestry and consultation rooms project out of the south face.

The land falls away at the rear and long and narrow openings provide ventilation into the understorey and then up into the chapel via floor louvers behind the altar.

The wide balcony choir loft is tiered and overhangs the entire west end of the nave forming a low-ceilinged entry zone supported on slender square concrete columns.

[1] The north and south walls are yellow face brick and the windows are positioned so they are shielded from the nave and their light is directed eastward onto the altar.

The pews are darkly-stained timber and are crafted to sit on the sloping floor, progressively shorter towards the altar to suit the reducing width of the nave.

The altar is made of large thick slabs of Helidon sandstone with the front carved with the Greek letters alpha and omega.

[1] On the southern side of the forecourt is a World War II memorial, a large sandstone monolith, standing within garden beds and grass and flanked by two steel flagpoles.

[1] Chapel of St Peter's Lutheran College, Indooroopilly was listed on the Queensland Heritage Register on 7 December 2012 having satisfied the following criteria.

[1] The place is an exceptional example of the work of architect, Dr Karl Langer, embodying architectural principles he developed and refined over his career.

The sculptural qualities of the austere chapel interior-including the seamless curving east wall with floating Cross; use of white plaster finishes complementing timber panelling and pale brickwork; natural lighting from the west facing clear glazing in the bladed side walls and from glazing in the west wall-evoke feelings of awe and reverence.
