A portion of a circular brick structure has been unearthed by archaeologists at Porpanaikottai, a Sangam-age site, in Pudukottai district.
According to T. Thangadurai, excavation director, the structure was contiguous to a three-course brick structure, exposed in the A1 trench within a few days after the Archaeology Department commenced digging at the site on May 20. A Sangam-age fort is believed to have existed here.
“The brick structure was found at a depth of 3.8 centimetres in Za1 trench. Its diameter is 230 centimetres. We have exposed portions of a couple of water channels built with bricks. A couple of brick structures have been found at a depth of 32 centimetres in the adjacent trench (Za2), too. One of them runs to a length of 200 centimetres,” Mr. Thangadurai said. However, it would require more digging to assess the nature and purpose of the structures, he added.
