St Peter's Seminary, Cardross

Following a fire in 1946 at St. Peter's Seminary in the Glasgow suburb of Bearsden, a new home was needed for the seminary. Discussions began with Gillespie, Kidd & Coia in 1953, but the plans for a new college in the village of Cardross were not finalised until 1961, when building began. The college had since moved from Bearsden to temporary homes. The seminary's philosophy students were transferred to Darleith House in Cardross and the theology students to Kilmahew House.[6][7] The plan was for a new building to accommodate all the students at Kilmahew House. It was a baronial mansion at the centre of the Kilmahew estate, a Victorian designed ornamental landscape created by the Burns family in the late 1800s. The mansion, built in 1865–1868, was originally a family home for James Burns and his son John, and later the Allan family, from the early 20th Century until just after the war, when the estate was sold to the Roman Catholic Archdiocese of Glasgow. Gillespie, Kidd & Coia employees Isi Metzstein and Andy MacMillan developed a radical design in which the old house would become professorial accommodation, and around it would wrap a striking new main block, a convent block, a sanctuary block and a classroom block. The old house thus became one side of a quadrangle, creating a bold juxtaposition between old and new buildings.

Determinedly modernist, brutalist and owing a huge debt to Le Corbusier, the seminary is widely considered to be one of the most important examples of modernist architecture in Scotland. Architecture critic Jonathan Glancey wrote:

The architecture of Le Corbusier translated well into Scotland in the 1960s. Although the climate of the south of France and west of Scotland could hardly be more different, Corbu's roughcast concrete style, could, in the right hands, be seen as a natural successor or complement to traditional Scottish tower houses with their rugged forms and tough materials.[8]

By the time it was completed in 1966, the number of candidates entering the priesthood had begun to decline. As a result, the building never reached its full capacity of around 100 students. From the outset, the building was riddled with problems, including maintenance difficulties with such a unique structure and significant water entry; the architects and owners each blamed the other for these problems.

In February 1980, the buildings closed as a seminary. The Archdiocese of Glasgow moved St Peter's College to Newlands in southern Glasgow. St Peter's College, Newlands, remained until November 1984 when it was closed and transferred its students to Chesters College in Bearsden, Glasgow. The Cardross site subsequently becoming a drug rehabilitation centre in 1983. Due to maintenance problems with the modern buildings, their attempted use ended by 1984 and vandalism to them began soon afterwards. The drug rehabilitation centre, now confined to Kilmahew House, closed in 1987. Maintenance of Kilmahew House ended in the early 1990s, higher palisade fencing was erected in 1992 in an attempt to curb vandalism. In 1995, a fire so badly damaged Kilmahew House that it was deemed too unsafe to stand and was demolished. The remaining modern buildings had been Category A listed by Historic Scotland in 1992,[3] and in October 2005 was named Scotland's greatest post-WWII building by the architecture magazine Prospect.[9]

Nonetheless, the building remains a ruin. Most of the woodwork and glass is now gone, although key aspects of the original design are still clearly visible. According to the architecture writer Frank Arneil Walker, "nothing prepares one for the sight of the new grown prematurely old."[10] Attempts to convert and reuse it, or even protect it from further damage, have come to nothing – hampered by the unique design of the building and its remote location. Plans have included building a 28-unit housing development in the building's grounds, and stabilising the structure by stripping it back to its concrete skeleton, possibly fully restoring a small cross-section. This is a source of concern for conservation bodies including the Twentieth Century Society, who have placed it on their Risky Buildings Register, arguing that this would destroy much of the remaining fabric of the building.

Funded by Historic Scotland and the Archdiocese of Glasgow, Avanti Architects were appointed to undertake a Conservation Assessment of the buildings and landscape. In June 2007, it was announced that the building was to be included in the World Monuments Fund's 100 Most Endangered Sites list for 2008.[11] Also in 2007, developer Urban Splash became involved.[12] Urban Splash worked with architect Gareth Hoskins, and in 2009 environmental arts group NVA were awarded a grant by the Scottish Arts Council to develop temporary and permanent artworks as part of the redevelopment of the building and surrounding woodlands.[13] In 2011, Urban Splash pulled out of the project due to viability issues, and the Archdiocese of Glasgow reiterated its view that no commercial scheme will be viable for the site.[14]

NVA, however, continued their involvement with the site, working with local community groups, raising funds and developing plans for the partial restoration of the seminary buildings and interventions in the surrounding landscape. In 2010, NVA presented these plans at the 12th International Architecture Exhibition at the Venice Biennale. In 2012, the Scottish Government gave £500,000 for the building's regeneration by a Historic Scotland building grant.[15] Also in 2012, NVA began working in partnership with the Universities of Glasgow, Edinburgh, and Strathclyde on the 'Invisible College',[16] a research network which aims to radically reinvent the college's original teaching function for the present day. A 'college without walls', the Invisible College has involved organised events bringing together academics, local residents, architects, artists, and other interested parties on site for debate, discussion, and collaborative investigations in the landscape. There have been public talks about ruins, architecture and landscape in the nearby villages of Cardross and Renton, and in the Lighthouse in Glasgow. The college has also produced an 'audio drift',[17] a sound work layering together environmental recordings and interviews, designed to be listened to on portable MP3 players whilst walking through the landscape, and a guided walk[18] around the Kilmahew estate, in collaboration with the Royal Geographical Society. Local residents from Cardross have begun cultivating food in the ruined walled garden of the former estate, which once supplied food for Kilmahew House and later the seminary. Following on from this, in 2013, the Invisible College organised a series of events exploring the horticultural and food-producing aspects of the site. The Invisible College has been funded by the UK Arts and Humanities Research Council (AHRC).

A planning application was submitted on February 2013 by Avanti Architects and ERZ Landscape Architects for the regeneration of the Seminary.[19] Funding was secured from the Heritage Lottery Fund and Creative Scotland. A major clean-up was completed in 2016 which included the cleaning and de-risking of the buildings, consolidating salvageable vaults and documenting the surviving buildings. NVA presented a sound and light event for the public which was sold out.[20] However, in June 2018, NVA closed down due to the challenges facing it after a funding bid to Creative Scotland failed.[5] The Archdiocese of Glasgow remains responsible for maintaining, securing, and insuring the site, which they cannot sell, give away, or demolish, and call for public funding.
