The Peruvanam Temple in Cherpu, Thrissur District, is the site of the legendary Peruvanam Pooram, one of the oldest festivals globally, boasting a history of over 1400 years. Dedicated to Lord Shiva, the temple's ambiance and charm attract devotees and visitors from across Kerala. According to legend, the current Sree Kovil (sanctum sanctorum) was originally a tree where Lord Shiva meditated. Over the centuries, the festival has evolved to include two spectacular events: the Peruvanam Pooram and the Arattupuzha Pooram.

The festival features a grand procession where the deity is carried atop a decorated elephant, accompanied by six other tuskers and the renowned traditional percussion ensemble, pancharimelam. This event brings the entire Thrissur district together, making it a memorable occasion each year. Celebrated in the Malayalam month of Meenam (March-April), the Peruvanam Pooram creates a festive atmosphere filled with richly adorned elephants, vibrant percussion music, and unique rituals.

During the festival, Lord Shiva's deity remains a silent spectator while 23 temples actively participate. Historically, around 108 temples took part in the festival. The Pooram fills the city with its vibrant and cultural essence, drawing thousands to the temple premises. A magnificent elephant pageantry, where one of the tuskers carries the Thidambu—a replica of the presiding deity—is a highlight of the festival.

A major attraction is the Pandi and Panchari Melam performances, which last around four hours until dawn. These performances take place in the Peruvanam Nadavazhi, a natural theater for such events. The Urakathamma Thiruvadi was the first to perform the Panchari Melam at this venue, and the Cherpu Bhagavathy Temple introduced the Nettipattams (caparisons for elephants) at Peruvanam Pooram.

Deeply rooted in rich traditions and culture, Peruvanam Pooram's history dates back to AD 583, making it one of the oldest organized ritualistic festivals. Initially, 108 temples under the Peruvanam Kshetra sanketham participated, but now only 23 temples partake. The festivities include numerous Ezhunnallippu (processions) with caparisoned elephants, traditional percussion ensembles like Panchari Melam and Pandi Melam, and vibrant cultural displays.

The festival begins with the procession of Pisharikkal Bhagavathy, setting all events in motion. The main Pooram features Arattupuzha Sastha, arriving before sunset with seven decorated elephants, followed by an elaborate Pandi Melam. Other significant processions include Chathakudam Sastha, Urakatthu Ammathiruvadi, and Cherpu Bhagavathy. Each procession is marked by intricate performances and traditional rituals, concluding with the grand Panchari Melam.

The Peruvanam Pooram culminates with a ritual bath for all participating deities at the temple pond, Thotukulam, symbolizing the festival's conclusion. The rich history, cultural significance, and grandeur of Peruvanam Pooram make it a cornerstone of Kerala's festive traditions, attracting spectators and devotees from all walks of life.
