Known as the “dimples of Venus,” the little indentations on the lower back have a special position in the realm of physical beauty. These dimples, which are formally called fossae lumbales laterales, are situated close to the top of the buttocks, directly above the junction where the spine and pelvis meet.
The term “dimples of Venus” refers to the Roman goddess of love, beauty, and desire, Venus. This moniker reflects the historical perception of these indentations as physical representations of attraction.

The sacroiliac joint’s anatomy, not muscles as one might assume, is what creates the dimples. The sacrum, the triangle bone at the base of the spine, and the iliac spine of the pelvis are joined by this joint. Where the skin is attached to these underlying ligaments, a shallow depression is formed, which is where the dimples appear.
