Obzor (Bulgarian: Обзор; Greek: Ναύλοχος - Naulochos; Latin: Naulochus, Tetranaulochus, or Templum Iovis) is a town in Bulgaria on the Black Sea coast. The Thracian name of Obzor was Naulochos, a small port on the coast of Thrace, a colony of Mesembria. The ancient Romans named it Templum Iovis (Temple of Jupiter); Pliny called it Tetranaulochus. (Strabo vii. p. 319, ix. p. 440; Plin. iv. 11. s. 18.)
