If you were a bit concerned reading the title of this post let me set your mind at rest. A sexfoil is a 6-petalled (or 6-leafed) shape. Gothic architecture features a lot of different numbered foils - trefoil, quatrefoil, cinquefoil, septfoil etc. In this instance the sexfoil is one of many that alternate with cinquefoils in the cloisters of Salisbury Cathedral. The reason I photographed the top of the cathedral tower and the bottom of the spire through it is for compositional reasons but also because it's difficult to get sufficiently distant to fit the whole building in the frame.
