It's early Byzantine fortress from the end of the 5th century during the rule of emperor Anastasius.
A great place in Bulgaria near the resort town Chernomorec which I visit quite often when I'm on my cycling trips. With this video, I want to show you the area and the beauty of the place.
Thank you for stopping by and I hope you enjoy it.
