The stone columns – the pillars are at the beach in front of the fishing village, east side to the temple. The photo you were mentioning is the query where they found the pre-historic skeleton. That place is at the west side to the temple, between the temple and the river mouth.
The stone pillars can be a kind of a maritime structure, belong to the harbour. They say it was a Jetty but no evidence to prove that European Types of Jetties were used in early periods. And that was a no place to build a Jetty. Didn’t find any remains of a settlement near the beach. Most of the artefacts, building structures and remains can be find inside and north to the temple.
