[2] Its site is located under modern Kastelli-Kissamou,[3][4] where travelers in the 19th century observed 14 or 15 fragments of shafts of marble and granite columns, an Ionic capital, and remains of walls, indicating that there once existed upon this site a flourishing and important city.
In 69–67 BC the latter city was destroyed by the Romans and Cisamus became the main port of Polyrrhenia.
The excavations show that the town was heavily expanded at the beginning of the Roman rule.
Rescue excavations of the last decades brought to light substantial remains of the town.
These remains include parts of cemeteries, several bath houses and many urban villas several of them well equipped with mosaics.
