Vadakkumnathan temple, one of the most unique, ancient and important of the sacred shrines of Kerala, It stands on a beautiful hillock at the centre of Trichur overlooking the town. The vast maidan around the temple is called Tekkinkadu or forest of teak woods and Trichur town literally revolves round the temple.
Thus we have three main shrines in the temple, dedicated to lord Siva, lord Vishnu and Sankaranarayana. Behindlord Siva, the goddess Parvati was also installed by Parasurama. This image is of wood and hence no abhisheka is performed for this deity. All other idols are of stone except that of Vadakkunnathan which is a mound of ghee. This is again a unique feature of the temple.
