An intriguing structure identified as a Heroon, a place that has been interpreted as being dedicated to founder of the city, though constructed around a century after the death of this unnamed figure.
It was built on the western edge of the agora around 510-500 BC. It was a low tumulus with a walled rectangular enclosure faced with large stones around it. Following the Roman acquisition, the shrine was buried and walled in. Though it was no longer in use, the Romans seemed to have respected the sanctity shrine for the most part, not building over it as was the case for most of the rest of the area.
When it was excavated in 1954 a low stone chamber with a pitched roof was discovered at the center, half below the surrounding ground level and half above. This contained several large, rare, and splendid bronze vessels, perhaps not locally-made, and a large Athenian pottery black-figure amphora of about 520–500 BC. The bronze vessels had traces of honey inside.
