Ayyankulam is an important landmark in Thanjavur. It is a tank which belongs to the Konganeeswarar temple located opposite. Although this a well-known landmark, similar to other water bodies in Tamil Nadu, this tank is also ignored and partly used as dump yard by the locals. Hardly few people know the beautiful stucco images and mural paintings that are found on the walls of the mandapa on the banks of this tank.
This tank can be dated back to 16th or 17th century CE (Thanjavur Nayaka Kings period). The colorfully painted stucco images and mural paintings that are found here belong to the same period.
Some of the images/paintings that are found here include Pattabhishekam of Ram, ten avatars (Dashavatars) of Vishnu, Ravana trying to lift Kailash, Nataraja, Bhairava, Dakshinamurti, Vishnu and Agni.
