The stairs in the Chapel of St Leger or St Lawrence on the Bridge over the River Great Ouse at St Ives
The stairs down to the crypt under the chapel. We are reliably informed that Sir. Harry Secombe negotiated this very narrow flight when he presented 'Songs of Praise' from the Chapel a few years back, it about 2 feet wide! - He made it and did a grand job.
