Haliaetum was a Roman port on the northern Adriatic coast of the Istrian peninsula.
The port was first established around 178-177BC following fierce resistance by the Histri, the indigenous population.[1] The site of the port is at Valižan on Simonov zaliv (Simon’s Bay) to the southwest of the modern town of Izola in Slovenia. Remains visible at extreme low tide include parts of its pier as well as various port buildings.[2] Some excavations were carried in the last years and they are planning to do more excavations in the future. The site is also opened for turists.
