Ettumanoor Mahadeva temple is an ancient Shiva temple in Kottayam, Kerala, India. Temple tradition has it that the Pandavas and the sage Vyasa had worshipped at this temple. The name of the place has its origin from the word manoor, which means “the land of deer.” The temple is one of the major Shiva temples in Kerala, along with Vaikom Temple, Chengannur Mahadeva Temple, Kaduthruthy Mahadeva Temple, Ernakulam Shiva Temple, Vazhappally Maha Siva Temple, Vadakkunathan temple and Sreekanteswaram Mahadeva Temple, Thiruvananthapuram.
The present temple building, with its gopuram and the fortress around it, was reconstructed in 717 ME (1542 AD). There are Dravidian mural paintings on the walls inside and outside of the main entrance. The fresco of Pradosha Nritham (Dance of Shiva) is one of the finest wall paintings in India. There is a golden flagstaff inside the temple topped with an idol of a bull surrounded by small bells and metal banyan tree leaves. In terms of architecture, these temples stand out to be an ultimate testament for the Vishwakarma Sthapathis for their engineering skills. The temple roofs are covered with copper sheets, and it has 14 ornamental tops. Bhagavathi, Sastha, Dakshinamoorthy, Ganapathy and Yakshi are installed here as subordinate deities. There is a separate temple for Lord Krishna. It is believed that the philosopher Adi Sankaracharya wrote ‘Soundarya Lahari’ while staying in the temple.
The origin of the name Ettumanoorappan is from Kattampakk, a small village in Kottayam district. Ettumanoor Mahadeva Temple hosts the arattu festival, celebrated on a grand scale on the Thiruvathira day in February–March each year.
Many people come to the temple on the 8th and 10th day of the festival, when seven and a half elephants (in Malayalam: ezharaponnaana) made of gold (nearly 13 Kgms) will be held in public view. This statue was donated to the temple by a travancore maharaja. The temple, one of the wealthiest Devaswoms in Kerala, has many valuable possessions.
The Thulabharam is one of the important rituals of this temple. People make offerings to God for favors received. On balance, the child or man for whom offerings were promised to God, is weighed against offerings ranging from gold to fruits.
