High villages of the Carpathians

There is no single answer - it depends how you count. By absolute height the highest permanent settlement is Verkhniy Yalovets in Bukovyna (upper edge ~1410 m). By average height the almost-abandoned Vypchyna leads (~1240 m: a few houses and a church). The highest PERMANENTLY inhabited place with real residents is Sarata (~1185 m, about a dozen people). Dzembronia, often called the highest, spreads from ~800 to ~1100 m: its upper hamlets are among the highest, but the "highest village" title is more touristic than official. And the highest settlement of all is the Dragobrat ski resort (~1300-1400 m), though it is seasonal.

Yes. The highest building in the Ukrainian Carpathians is the restored "White Elephant" observatory on Pip Ivan Chornohirskyi (2002 m). Religious structures also stand above the villages: a chapel on Radul polonyna (~1540 m), churches and monasteries on the meadows. And every summer the shepherds' polonyna huts come alive - seasonal "settlements" up to ~1500 m, where cattle graze and brynza cheese is made. So permanent villages above ~1200 m barely exist, but temporary and special high-mountain dwellings are plentiful.
