  Following the early prediction of the skyrmion lattice (SkL) - a periodic
array of spin vortices - it has been observed recently in various magnetic
crystals mostly with chiral structure. Although non-chiral but polar crystals
with C$_{nv}$ symmetry were identifed as ideal SkL hosts in pioneering
theoretical studies this archetype of SkL has remained experimentally
unexplored. Here, we report the discovery of a SkL in the polar magnetic
semiconductor GaV$_4$S$_8$ with rhombohedral (C$_{3v}$) symmetry and easy axis
anisotropy. The SkL exists over an unusually broad temperature range compared
with other bulk crystals and the orientation of the vortices is not controlled
by the external magnetic feld but instead confned to the magnetic easy axis.
Supporting theory attributes these unique features to a new non-chiral or
N\'eel-type of SkL describable as a superposition of spin cycloids in contrast
to the Bloch-type SkL in chiral magnets described in terms of spin helices.
