Thirunakkara Temple is located in Kottayam Town in Kerala. At Thirunakkara Mahadeva Temple, Lord Shiva is worshipped in a benign and calm form. The natural formed, or Swayambhu, Shivling is six inches tall. The temple is famous for Pakalpooram and the Shivratri Festival.
Thekkumkoor Raja constructed the temple around 500 years ago. The temple bears striking resemblance to the famous Vadakkunnathan Temple in Thrissur. This is because, the king is believed to have darshan of Vadakkunnathan in his dream.

The main sanctum sanctorum contains Swayambhu Shivling and a small murti of Goddess Parvati.
