A special feature of the temple is its Rajagopuram, facing the north, with beautiful carvings on its lower wall. Those whose marriages are delayed, those, who have angaraka dosha and those who are childless can offer worship here and be blessed. This temple is also called Sevvaikizhamai koil because it is glorified as an angarakasthalam. On the Tuesdays in the Tamil month of Maasi, devotees throng this temple in huge crowds. They fulfill their prayer commitments once their prayers are granted. Another special feature is that the sun offers worship to the Lord by making his rays fall on the deity in the sanctum for five consecutive days in this month.
