On a trip to the Dharmasthala, tourists 'must visit' the Dharmasthala Temple that is situated at the west of Ratnagiri Hill. This temple was constructed about 500 years ago by Jain Chieftain, Brimanna Pergadem. Dharmasthala Temple enshrines the golden linga of the Lord Shiva. Shri Manjunatheshwara Annappa Swamy, an incarnation of the Lord Shiva is the chief deity of the temple.
The linga in this pilgrimage site was taken from Kadri that is situated in proximity to Mangalore. Upon reaching the site, tourists would get the chance to see the Nrusimha Saligrama (one of the avatars of Lord Vishnu) that has been placed beside the linga.
The sanctum sanctorum of the temple has shrines of Lord Maha Ganapati and Goddess Ammanavaru or Parvathi. In addition, this temple has shrines and images of four Dharma Daivas (Guardian Spirits of Dharma), namely Kannyakumari, Kalarkai, Kalarahu and Kumaraswamy.
Like other temples in Kerala, the inner circle of the Dharmasthala Temple has been built using wood. The unusual thing about this temple is that the site is managed by Jain administration and puja is organised by Hindu priests of Madhva order. Devotees can visit the Dharmasthala Temple from 6 am to 2 pm and 6:30 pm to 8:30 pm.
