Klaros never served as a city throughout its long history, but rather as a sanctuary to Apolio during the Hellenistic period, and as an important oracle and sanctuary during the Roman period. Since it was so close to Kolophon and Notion, the faithful citizenry maintained their homes in these two cities.

He would be told only the names of the clients, nothing more, then would descend to the oracle under the temple. Here he reportedly drank from a sacred well and meditated. Later, he could emerge to advise the waiting people on the matters that had been of most importance to them. What Is more he did this in verses.
