Triport or Treport is a cape and historic harbor on the Adriatic Sea northwest of Vlorë, Albania. It is located in Vlorë municipality, and constitutes the northern limit of the Bay of Vlorë. Located 5 km northwest of the city, the harbor of Triport is the Fishing Port of Vlorë. It is one of the most important fishing ports of Albania, featuring the country's second largest fishing fleet.
Vlorë (/ˈvlɔːrə/ VLOR-ə; Albanian: [ˈvlɔɾə]; Albanian definite form: Vlora) is the third most populous city of Albania and seat of Vlorë County and Vlorë Municipality. Located in southwestern Albania, Vlorë sprawls on the Bay of Vlorë and is surrounded by the foothills of the Ceraunian Mountains along the Albanian Adriatic and Ionian Sea Coasts. It experiences a Mediterranean climate, which is affected by the Ceraunian Mountains and the proximity to the Mediterranean Sea.
The coastal area of Vlorë was one of the Illyrian sites that had experienced pre-urban activity beginning from the 11th–10th centuries BC. The area was colonized by Ancient Greeks. A large fortified port-town that was inhabited from the 6th century BC to the 2nd century AD is placed, now partially submerged, in Triport, northwest of present-day Vlorë. Substantial port activity in this site occurred from at least the archaic period to the medieval period. It has been suggested that a transfer of the ancient city from the site of Triport to the site of modern Vlorë occurred. The center of the modern city features archaeological remains dating from late antiquity. Aulon, from which the modern city took its name, appears in historical sources starting form the 2nd century AD. It was conquered at different periods throughout history by Romans, Byzantines, Normans, Venetians and Ottomans.
Thronion (Ancient Greek: Θρόνιον) was an Ancient Greek city on the Illyrian coast, in the Bay of Vlorë on the southern Adriatic Sea. Although the earliest contacts appear to have been more pre-colonial activity rather than permanent settlement, an ancient, still archaeologically unproven tradition claims that the city was founded as a Locrian–Euboean colony on the fringes of the territory of the Amantes. Thronion was located to the south of the territory of Apollonia and in front of the Acroceraunian Mountains, the natural boundary between ancient Epirus and Illyria. Thronion was conquered by nearby Apollonia before 460 BCE.
Thronion has been identified with the site of Triport northwest of present-day Vlorë, Albania, where a large fortified port-town that was inhabited from the 6th century BCE to the 2nd century CE is found now partially submerged.
