Tiruchengode Arthanareeswarar Temple is a famous attraction of Namakkal. Dedicated to the androgynous form of Lord Shiva, this temple is located atop a hillock at the altitude of 900 meters. Ardhanareeswarar is composed of Shiva and his consort Shakti or Parvati, representing the synthesis of the male and female energies. The mythologies behind this temple say that Lord Shiva gave his left half to his wife so that they would never have to be separate. Thus, Shakti or Parvati became inseparable from the male precept of Lord Shiva.
The Goddess is known as Ardhanari. The iconography of Ardhanareeswarar is depicted as half male and half female, and it is separated in the middle.
