One of Scotland's most lauded modern buildings, St Peter's Seminary in Cardross, which for years has lain in ruins, has been given a £4.2m cash injection to aid its resurrection.

Plans to transform the modernist ruin into an arts and education centre by Glasgow arts company NVA have been backed by £3.8m in lottery funds from the Heritage Lottery Fund, with an extra £400,000 from Creative Scotland.

The news comes as NVA have unveiled its first public event at the building, the sell-out show light and music show, Hinterland, which is part of this year's Festival of Architecture.

St Peter’s opened as a training centre for young priests in 1966, with its design by Scottish architects Isi Metzstein and Andy McMillan of Gillespie, Kidd and Coia.

It closed its doors in 1980 and has existed as a ruin, frequently vandalised, ever since.

The new money will see elements of the building restored whilst others will be "consolidated" to allow the public safe access to large scale events and performance as well as to smaller community activities.

The chapel will be partially restored and converted into a 600-capacity venue while the former sacristy and crypt will be a focal point for exhibitions.

The plans include the 104-acre rural estate surrounding the architectural masterpiece – an estate which includes the remains of the 15th century Kilmahew Castle.The Herald:

A path network based on the original 19th century designed landscape will be reinstated, historic bridges restored and the Victorian walled garden brought back into productive use, bringing the site back to life and encouraging new audiences to visit.

It is expected that over 200 people will become involved as volunteers.The Herald:

Lucy Casot, Head of the Heritage Lottery Fund in Scotland, said: "After 25 years of decline, this ground-breaking project has the potential to save an internationally significant building, exploiting its commanding presence to produce an exceptional arts venue.

"Its appeal will attract new audiences from near and far. Its transformed estate will become a natural haven for the local community to explore, enjoy and be proud of.

"Highly regarded across the world, it is a unique record of its time which is in very real danger of being lost.”

Angus Farquhar, the Creative Director of NVA, said: "This is a historic moment in the life of St Peter’s Seminary. 

"We are now able to start work on its permanent transformation into an international cultural centre that will speak to the creative life of Europe.

"After the overwhelming response to Hinterland, our first major animation of the site and the new name for Kilmahew/St Peter’s, we have real hope that our vision for progressive, socially-focussed art will connect strongly with people and together we will forge a new place for public art and its significance in the world.

"We thank Heritage Lottery Fund and Creative Scotland for joining us in the vision and ambition for the site and investing in its future.”
