the town was named Kozyak and was part of the Karvun principality and the fortress, successor of the ancient town. The Ottoman conquerors ruined the fortress to the last stone. Its present name Obzor was given to the town in 1935.
The beach by the town is long and it extends from Cape St. Atanas on the north to the southern Cape Mona Petra. It is followed by a small nestling cove and a beach named Irakli. Once there was a village with the same name there, inhabited by Greek settlers who left it and settled to live with the Bulgarians in Obzor. Cape St. Nickola is several kilometres to the south where the Balkan Mountains touch the Black Sea. Then the central cape of the Stara Planina Mountain called Emine comes and it is considered to be the end of the Balkan Mountains. During the Middle Ages there was a fortress - Emona and the place around was called Paleokastro. Many monks and hermits lived in the rocks in those days and there were lots of small chapels and monasteries.
The village of Byala is situated not far to the north of Obzor. Once there was an ancient Greek fortress named Aspro. The camping site called Kristina is situated near the village. The wine of the extremely fine “Dimyat” vintage is produced in the village. There is a wonderful roadside establishment – Jackson Restaurant to the north on the road to Staro Oryahovo. The village of Emona near Cape Emine, to the south of Obzor is famous for being the birthplace of the Thracian king Rez. He participated in the Thracian War and was killed by Odysseus and Diomedus according to Homer’s Iliad.
