476 - 1186

Byzantine Dalmatia and Slavic coastal settlement reshaped the bay after Rome's fall. The Ostrogoths seized the area briefly, then Emperor Justinian built a fortress above Kotor in the 6th century—the origin of the city walls you climb today. The Byzantine name Dekatera (or Dekaderon) gave Kotor its modern name. Slavic peoples settled the coast from the 7th century onward, while monastic communities appeared on Miholjska Prevlaka by the 6th century and the Benedictines established themselves on Sveti Đorđe island by the 12th century. St. Mary Collegiate Church preserves early medieval Romanesque stonework from this transitional world.

1420 - 1797

The Venetian thalassocracy and Baroque maritime city-states transformed the bay into an Adriatic powerhouse. Venice ruled Kotor and Perast from 1420, building the fortified walls, Baroque palaces, and seafaring confraternities that define the region's visual identity today. The Boka Navy (Bokeljska mornarica), whose oldest surviving statute dates to 1463, became the civic custodian of St. Tryphon's feast and the kolo chain dance—now UNESCO-listed intangible heritage. In Perast, the Fašinada ritual—throwing stones to expand Our Lady of the Rocks island every July 22—has continued since at least 1452, maintaining an artificial sacred landscape. Meanwhile, Herceg Novi lived a different story: Ottoman rule from 1482 to 1687 left the Sahat Kula clock tower (built 1667), Kanli Kula fortress, and a confessional frontier visible in Savina Monastery's Orthodox resilience beside Ottoman walls. Forte Mare fortress spans both Venetian and Ottoman layers. This dual heritage—Venetian maritime Baroque in Kotor/Perast, Ottoman frontier in Herceg Novi—is the bay's most visitor-legible layer.

-400 - 476

The Illyrian Ardiaei kingdom and Roman Adriatic provincial integration define the Bay of Kotor's deepest layer. Rhizon (modern Risan) was the Illyrian capital commanding the inner bay from around 400 BC. Rome absorbed it into Dalmatia as Rhizinium, and a Roman maritime villa with geometric floor mosaics—depicting Hypnos, the god of sleep—proves this bay was a prized retreat two millennia ago. Walk through the Risan mosaics and you stand on the oldest urban floor in the Bay of Kotor.

1797 - 1918

The post-Venetian transition and Habsburg imperial navy brought a new military-industrial layer to the bay. After Napoleon dissolved the Venetian Republic in 1797, the Treaty of Campo Formio transferred the bay to Austria. The Habsburg Empire turned Boka Kotorska into its principal southern naval base: General Lazar Mamula built the circular fortress on the entrance island in 1853, and the naval arsenal in Tivat was constructed in 1889. The Maritime Museum in Kotor preserves the legacy of Boka's 19th-century merchant captains. Austro-Hungarian rule lasted until 1918, when sailors mutinied in the bay and the region joined the new South Slav state.
