The city was originally an important city during the rule of Pallavas in the 7th and 8th centuries. As per historians, the city was probably one of the capitals of their viceroys, the Muttaraiyars. During the regime of Vijayalaya Chola (848-71), the first medieval Chola emperor, the Muttariayars were defeated and the region came under Chola territory. The place was a capital city during the regime of Sundara (Parantaka II) (957-70). The city had palaces where members of the royal family resided even after shifting the capital to Thanjavur during the regime of Rajaraja Chola. There was only one palace for Vijayalaya Chola, but later individual palaces were built for all the princes. Rajaraja's sister Kundavai resided in the place and continued to issue orders and grants from the palace as seen in the inscriptions. Rajaraja I, who built the Big Temple of Thanjavur is said to have spent his last days in the city, the capital of his predecessors. During the regime of Rajendra I (1012-44), the capital was shifted to Gangaikonda Cholapuram, but the city Palayarai still retained its importance. The place started losing its importance during the late 12th to 13th centuries when the region was occupied by Pandyas. Systematic excavation was carried out in the place by the Department of Archaeology of the Government of Tamil Nadu in 1983-4 at Nandan Medu, Keezha Pazhayarai and Nathankoil. The excavations unearthed multiple dolmens and artefacts from the Chola regime. Though the region was predominantly occupied by Saivites and Vaishnavites, the verses from Appar during the 7th century indicate existence of Jaina colonies in the region, indicating a multi cultural coexistence. Buddha statues were also found in archeological excavations, indicating that Buddhism has flourished in the region. Temples
