The Thirumohoor Kalamegaperumal Temple, located near Melur in Tamil Nadu's Madurai district, is dedicated to Lord Vishnu and constructed in the Dravidian architectural style. This temple, revered in the Nalayira Divya Prabandham, is one of the 108 Divya Desams. Here, Vishnu is worshipped as Kalamega Perumal, with his consort Lakshmi as Mohanavalli Thayar. The temple is also known as Mohanapuram and Mohanakshetram, highlighting its deep spiritual significance in Hindu mythology.
A granite wall surrounds the temple, enclosing its shrines and three water bodies. The impressive five-tiered rajagopuram serves as the temple's gateway, while a large tank lies in front. The temple's origins trace back to the Pandyas, with notable contributions from the Madurai Nayaks. Daily rituals and major festivals, especially the Brahmotsavam in the Tamil month of Vaikasi, are vital to the temple’s spiritual life, attracting many devotees throughout the year.
According to Hindu legend, the temple’s name is derived from the story of Mohini, who deceived the asura Bhasmasura, ultimately leading to his defeat. Another narrative speaks of Vishnu's role during the churning of the Ocean of Milk, where he took on the form of Mohini to assist the devas. This rich tapestry of mythological history contributes to the temple's revered status and attracts pilgrims and tourists alike.
The temple’s architectural features include four prakarams and a sanctum housing Kalamega Perumal in a unique standing posture. Unlike other temples, the goddesses do not touch the deity’s feet, emphasizing its distinctiveness. The temple is adorned with intricate carvings and inscriptions that reveal its historical significance, including contributions from notable figures. Festivals celebrated here, like Vaikasi Brahmotsavam and Vaikunta Ekadashi, are vibrant events marked by rituals, music, and community participation, enriching the cultural landscape of the region.
