Religious significance.
The roof over the sanctum was constructed during different times, but is believed to be burnt by the power of Vekkali Amman. The position of the leg of Vekkali Amman is different from other Shakti temples without roof where the right leg is placed over demon. As per Hindu legend, the position requires lot of energy and while Nataraja, during his dance switched his legs, Vekkali Amman remained in the position to show her energy levels. The posture is also believed to signify kindness, love, affection and compassion to her devotees. Historically, temples facing north, are considered to provide victories on endeavours. The Cholas worshipped the deity before proceeding to military campaign. 
The people of Woraiyur see Vekkali Amman as the saviour deity during difficult times.
