Kuchanur, a small village near Chinnamanur in Theni district, as does Thirunallar, has a separate temple for Lord Saneeswara, unlike other places where He is part of the Navagrahas.Legend has it that King Dinakaran who once ruled Kalinganadu with Maninagaram as capital incurred Sani Bhagwan's wrath for Seven and half years.
Dinakaran's son Chandiravadanan on coming to know of it through an astrologer went to a dense forest and sat on a penance in the midst of Senbagam, Sandalwood and Kongu trees near the bank of Surabi river to invoke the blessings of Lord Saneeswara to set his father free from the curse.
Moved by his prayers, Lord Saniswara appeared before him at a place called Senbaganallur and granted his prayers. The place later came to be called Kuchanur. Kuchanur is one of the town Panchayat, is surrounded by channels and forests.
