Downstream from the confluence of its tributaries, the Trebižat and Bregava rivers, the valley spreads into an alluvial fan covering 20,000 hectares.

Nature Park "Hutovo Blato" is located in the South-Western part of Bosnia and Herzegovina, 30 km from City of Mostar and near the Croatian border.

Gornje Blato-Deransko Lake is supplied by the karstic water sources of the Trebišnjica river, emerging in the proximity of the bordering hills.

The find is unique in a European perspective and the archaeologists have concluded that Desilo, as the location is called, was an important trading post and a site of significant contact between the Illyrians and the Romans.

The archaeologists have discovered the ruins of a settlement, the remains of a harbour that probably functioned as a trading post, as well as many sunken boats, fully laden with wine pitchers – so-called amphorae – from the 1st century BC.

[12] The archaeologist Adam Lindhagen, who holds a PhD from the University of Lund and has specialised in Roman wine amphorae, says that this is the most important find of all time from the Illyrian areas.
