If you went for holidays to Sunny Beach, you were likely taken on a day trip to a "traditional" Bulgarian village in the Strandzha. You were probably offered some tourist animation in the form of old women spinning wool and baking banitsa, and then you went for a donkey ride.
That village, deep in the heart of the Strandzha, was declared a national heritage site as early as 1982. It is renowned for its period wooden houses, its interesting church and its balmy climate that is neither too hot nor too cold. It is about 60 km south of Sozopol, and many of its 66 permanent denizens go to spend the winter with their children and grandchildren in the big cities. A hint: in Bulgarian its name means "ivy."
