The QTSQ (Quarter To Six Quadrant) is the name given to the rural area lying immediately to the south and west of Cambridge, a mile or two from the built-up edge of the City. It lies mainly, but not wholly, within the four parishes of Barton, Coton, Grantchester and Madingley.
South Cambridgeshire District Council has designated the QTSQ as a Major Green Infrastructure Target Area.
