The prytaneum was the building where used as accommodation for other citizens but basically daily administrative operations were executed and the members of the Boule met.
Although it is difficult to see the remains dating from earlier than 2nd century B.C., it is believed that the Prytaneum was erected in the 2nd century. The entrance door of the edifice is in the middle part of the south side.
Prtytaneum is the place that the sacred flame of the city and dedicated to the goddess Hestia and all other hearths burned continually. In the room to the east of the entrance stands the Sacred Hearth in which the sacred fire burned. The hearth was made of rubble which was 30 centimeters and is believed to date from earlier periods.
