St. Peter’s Seminary is a disused Roman Catholic seminary near Cardross, Argyll and Bute, Scotland. Accompanied by a fellow dude and enthusiast.

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. Designed by the firm of Gillespie, Kidd and Coia, it has been described by the international architecture conservation organisation DOCOMOMO as a modern building of world significance. It is one of only 42 post-war buildings in Scotland to be listed at Category A, the highest level of protection for a building of special architectural or historic interest. It has been abandoned since the end of the 1980s, and is currently in a ruinous state. Despite a number of proposals for reuse or renovation of the building, its future remains insecure. Such a shame.
