Tiruvidaimarudur has a Siva Temple namely Mahalingha Swamy with the Goddess Brahath Sundara Gujambal(In Tamil, it is Perunala Mamulai Ammai). Shiva is worshiped as Mahalingeswaraswamy, and is represented by the lingam. This lingam, known as Jothimayalingam  is “believed to be the focal point for the seven consorts of Shiva.”  The Nandhi in the Temple is one of the largest in the district, of course it is not made of a single stone, that is why it is not weighted more than the Brahdeshwara Temple at Tanjore though it is bigger in size than that. There is a separate Sannathi for "Moogambigai" with Maha Meru. There are 149 inscriptions found in the temple which indicate the “contributions from Pandyas, Cholas, Thanjavur Nayaks and Thanjavur Maratha kingdom.” The present masonry structure of the temple was built during the Chola dynasty in the 9th century. Later the Thanjavur Nayaks expanded the temple during the 16th century. Two temple festivals are being celebrated for 10 days - "Thai Poosam" In January- February and another one, Thirukkalyana Uthsavam (Vasantha utsavam) in Vaigasi (May). 63 Nayanmar Ula and Aruthra Darshan( like in Chidambaram) are the other two important temple festivals. There are 27 star lingas, the prince "Ammani Ammal" Vigragam and Chitra prakaram(enclosed precincts of a temple) which is full of painting. There are several charitable trusts, one of them being "Pachhiyappa Mudhaliyar ArakattaLai". Notable People
