Rowena Baxter regularly waits for the Park and Ride bus outside St John's College, Cambridge, and being an observant birder, she could not fail to notice the decline in Swifts in recent years, so she arranged for us to explore opportunities for Swift nest-boxes somewhere on the site together with Dr R. E. McConnel, a college fellow, and Steve Beeby, Superintendent of Buildings.
To quote from their website: "St John's College is one of the oldest and largest colleges in Cambridge. Former students include famous business and political leaders, as well as renowned scientists and artists. It's an inspiring place to study, or even just to visit."
For a college that was founded in 1511, one couldn't exactly go hanging Schwegler swift boxes around the buildings, so we cast our sights on the chapel tower.

|8 nest-boxes in 4 cabinets|
There are 3 sets of louvres on each of the 4 sides of the tower, with openings behind 'bird proof' mesh at floor level. It was decided to place 4 2-box cabinets behind the openings on the west side.
Permission was granted by the dons and other college authorities.
Bob Tonks designed, built and installed the boxes. A Box of Swifts, driving two speakers, is barely audible at ground level. Should we succeed in attracting Swifts into these boxes, there is plenty of opportunity for expansion.
