Ettumanoor is located 12 Kms north-east of Kottayam town. The ancient Siva temple here has brought glory and fame to the place. Myths have it that the Pandavas and the sage Vyasa had worshipped at this temple. The name of the place had its origin from the word 'manoor', which means the home of deer. The arattu festival of this temple is celebrated on a grand scale on the Thiruvathira day in Kumbham (February-March) every year. A large number of people flock to this temple on the 8th and 10th day of the festival when seven and a half elephants made of gold (nearly 13 Kgms) will be held in public view. The temple, the wealthiest Devaswom in Kerala, has many valuable possessions.
