Excavation conducted at two locations at Maligaimedu revealed the remains of royal palace, built with burnt bricks. The ceilings were covered with flat tiles. The pillars were probably made of polished wood, supported on granite bases. Excavations revealed brick walls about 1.10cm in thickness. On the foundation wall, granite stone pillar bases were embedded at an equal distance of 2 meters. Bone objects with animal figures, ivory
carvings, quartz beads, shell bangle pieces and stone objects were found during the excavation. The excavation also yielded celadon ware and porcelain
sherds. Both of them are of Chinese origin. This shows the contact of the Chola
kingdom with China during
11th to 12th centuries CE.
