Statement of Special Interest

St Peter's seminary was commissioned in 1958 by the Archbishop of Glasgow. Now redundant it has been systematically vandalised and is now reduced to a ruinous skeleton. Designed by innovative architects, Metzstein and McMillan (who ran the Gillespie, Kidd and Coia architectural practice after the war (overseen by Jack Coia) it is hailed as one of the finest modern buildings of the day and was recognised as such when it was awarded the prestigious RIBA Architecture award in 1967. Influenced by the architecture of Le Corbusier and in particular his monastery of La Tourette, they took the traditional monastic plan and reshaped it to form a totally modern idiom in terms of planning, of interrelated spaces which are expressed on the exterior by the change of form and materials and with technical virtuousity they achieved a complex of buildings of amazing effects and sculptural quality. Kilmahew House was demolished in 1995 following fire damage.

About Designations

Listed Buildings

We list buildings of special architectural or historic interest and these are selected according to criteria published in the, Annex 2, pp74-76.

The information in the listed building record gives an indication of the special architectural or historic interest of the listed building(s). It is not a definitive historical account or a complete description of the building(s). The format of the listed building record has changed over time. Earlier records may be brief and some information will not have been recorded.

Enquiries relating to works to listed buildings should be made to the local authority in the first instance. Listed building consent is required for works which a local authority considers will affect its character as a building of special architectural or historic interest and local authorities also decide if listed building consent is required.

Listing covers both the exterior and the interior. Listing can cover structures not mentioned which are part of the curtilage of the building, such as boundary walls, gates, gatepiers, ancillary buildings etc. The local authority is responsible for advising on what is covered by the listing including the curtilage of a listed building. For information about curtilage see

Legislation introduced on 1 October 2015 allows us to state that: an object or structure fixed to the listed building; any object or structure within the curtilage of the listed building; and, any part or feature of the listed building that is not of architectural or historic interest may be excluded from a listing. If part of your building is not listed under the new legislation, the part will be excluded in the statutory address and in the statement of special interest. The statement will use the word 'excluding' and quote the relevant section of the Historic Environment Scotland Act 2014. Some earlier listed building records may use the word 'excluding', but if the Act is not quoted, the record has not been revised to reflect current legislation.
