Artemonas is named for Artemis, Apollo's twin sister, and is a mere kilometer from Apollonia. Apollonia and Artemonas are twin cities, theoretically. Artemonas is the second largest island village on Sifnos. Its windmills and several churches make it a charming spot to visit.
Down on the coast is the lovely church of Panagia Poulati with a nice beach below it.
