Church building
St John's Kirk, also known as St Winnock's Church and, colloquially, Auld Simon (Old Simon), is a ruined church in Lochwinnoch, Renfrewshire, Scotland. The church's lintel dates to 1729. Only the southwest gable and a single bay of the original structure remain; the rest was likely demolished around the time the new church was built in 1808. The church and surrounding walled cemetery was Category B listed in 1971.
