Present-day Mannargudi dates from the time of the Thanjavur Nayak king, Vijaya Raghava Nayak (1633–1673), also called "Mannaru dasan" who carried out extensive renovations of the Rajagopalaswami temple complex and is credited by some with having reclaimed the land from the surrounding forest.
In the Malika, Sri Sastrigal had composed songs on the annual rituals and important festivals being celebrated at Sri Tyagaraja Swami Temple Tiruvarur, and Sri Rajagopala Swami Temple, Mannargudi.
