What the sources say
“The alar ligaments limit axial rotation and lateral flexion on the contralateral side and, apart from the transverse ligament, are the strongest stabilisers of the atlas preventing anterior displacement in the event of rupture of the transverse ligament.” Offiah and Day 2016
“Together with the transverse ligament (transverse atlantal ligament; see below), the alar ligaments are primary stabilisers of the craniocervical junction.” Offiah and Day 2016

Where the skull meets the spine. The atlas carries the skull, the axis lets the head turn, and a small set of ligaments, above all the transverse ligament, holds the joints together.
