The T.N. Department of Archaeology, in association with the Public Works Department (PWD) has commenced conservation and maintenance work at the Vishnu temple, a protected monument located in Ulagapuram near Vanur in Villupuram district.
The temple is said to date back to the 11th century A.D and the village was then known as Olagamadevipuram, named after the chief queen of Chola King Raja Raja I.
According to D. Ramesh, Assistant Professor of History, Arignar Anna Government Arts College, Villupuram, “The temple was called Arinjaya Vinnagararm temple, named after the Chola ruler Arinjaya Chola. It was built during the period of Rajendra Chola, and a stone inscription in the temple revealed the presence of two tanks: Gandaradityapereri and Kalakandapereri.”
