As Rhiannon says this tree-covered barrow marks the breast of the Virgo figure in the ‘Glastonbury Zodiac’. Virgo is the fertile Earth Mother, and Wheathill lies at her feet. Her profile and front are outlined by the River Cary, and she is lying on her back, her head pointing west. Barrows are often breast-shaped, and ‘toot’ is a apparently a variant of ‘teat’. Wimble Toot certainly resembles a breast lying on the fertile farmland.
Wimble Toot lies between Steart Lane (near Bowers Farm) and the nearby River Cary. It's a small conical mound, ten feet high and crowned by a group of trees - it's probably a Bronze Age round barrow.
If you go for that sort of thing, it's part of the "Glastonbury Zodiac". Of course, it's Virgo's breast.
