Harbour of Eleutherios

The Harbour of Theodosius (Latin: Portus Theodosiacus, Ancient Greek: λιμήν Θεοδοσίου) was one of the ports of ancient Constantinople, the capital of the Byzantine Empire, located beneath the modern Yenikapi neighbourhood of Istanbul, Turkey. It was built at the mouth of the Lycus watercourse that ran through the city to the Propontis (the Sea of Marmara). It may have been on or near the Harbour of Eleutherios (Medieval Greek: λιμήν Ἐλευθερίου) which is still unlocated in this area. The harbour was built in the late 4th century, during the reign of Theodosius I, and was the city's major point of trade in Late Antiquity. It continued to be used until the 11th century. Silt from the Lycus creek eventually filled the harbour entirely and the area was later transformed for agricultural use due to the effects of upstream erosion and deposition. In Ottoman times, the area was built over. The harbour was located on the south side of the peninsula on which the city is built, on the shore of the Sea of Marmara. The other harbours on the southern coast of the city were the Harbour of Julian and the small harbour of the Boukoleon Palace. The harbours of Neorion (Latin: Neorium) and Prosphorion (Ancient Greek: προσφόριον, lit. 'import harbour', Latin: Portus Prosphorianus) were on the Golden Horn, on the northern shore of the peninsula. Today the northern coast of the harbour is delineated
