In the 14th century the valley was invaded by Bosnian kings Stjepan II. Kotromanić, Tvrtko and Herceg Stjepan Vukčić Kosača, as well as the counts Radivojević, Jurjević and Vlatković. The Turks built a tower at Kula Norinska in the 15th century for easier control of the traffic across the Neretva Valley; the remains of this mighty tower are well preserved and can be seen off the main road between Metković and Opuzen.
The role of Roman Narona was taken over by the port town of Drijeva, which was probably situated on the right bank of the river Neretva in today’s Gabela. It is believed to have been a major trading post for a wide range of goods, such as cloth, wax, salt and spices, as well as slaves. It was mentioned frequently by public notaries in the Republic of Dubrovnik. These also mentioned the town of Metković in the 15th century, in a document from 1422 kept at the State Archive in Dubrovnik. Metković was first depicted on a map in 1570 by Venetian cartographer Jacopo Gastaldi. The 15th and 16th centuries were characterized by conflicts between the Turks and the Venetians. The Treaty of Požarevac in 1718 determined the border between the Turkish Empire and the Venetian Republic. After this the Venetians destroyed and abandoned Gabela and founded a new port on the River Neretva, in today’s Metković.

The best example of a rich and diverse bird population of the Neretva delta can be observed in the ornithological collection in Metković. Founded by famous Croatian ornithologist Dragutin Rucner. Unfortunately, the dalmatian pelican, griffon duck and marbled teal are gone, but even today we can see bitterns and ferruginous ducks nesting in the Neretva delta.
