Greek archaeologists have discovered the "well-preserved" remains of a large Bronze Age town dating from at least 1,900 BC on the Cycladic island of Andros, the culture ministry said in a statement on Wednesday.

Archaeologists found at least four "well-preserved" buildings - one of them retaining its ground floor walls - in the remains of a quarter, and a graded road believed to lead to a square.

A variety of mainly ceramic objects was discovered inside the buildings, including large decorated storage jars, pots and vessels, and stone tools, many of them intact.

Researchers also found a number of rock drawings on the edge of the town, which lies on the south-western Cape Plaka near the fortified site of Strofilas, a Neolithic settlement that dates from 4,000 BC.

The drawings portray boats and a combination of other symbols -- a human head surrounded by a pair of arms with open palms, a pair of feet and a circular symbol believed to represent the sun -- that archaeologists suspect corresponds to a divinity worshipped by the town dwellers.

The symbols are similar to sketches found at Strofilas, suggesting that the fortified community's inhabitants moved their lodgings closer to the sea at the end of the Neolithic period, around 3,300 BC.

The still-unnamed coastal town, which provides a "strong link" between the end of the Neolithic period and the Bronze Age in the Cyclades, is suspected to have suffered repeated damage from earthquakes, the ministry said.
