Agia Sotira is situated on the northeastern side of the Messinian peninsula at an altitude of 150m, with approximately 50 residents. The village was created after the movement of several residents from an older village built around the chapel of Metamorfosis tou Sotiros (Transfiguration of Jesus), from which it took its name. The older village was completely abandoned, but a few stone-built houses are still well preserved.

The village is sparsely populated, since much of the area was unavailable due to the older cottages not being cleared away. Almost all of the approximately 80 houses are now renovated or newly-built.
