St Peter's seminary, Cardross, Scotland.
Built in the mid 1960s but finished just as there was a serious decline in the number of people entering the priesthood, so as a seminary it closed in 1980. Was then used as a drug rehabilitation centre until the late 1980s.
Now a ruin though there are planning applications in for its development.
