This village is known for the annual Pooram festival at the temple in April/May. The uniqueness of this festival is the ceremonial processions carrying the images of the deities of 41 neighbouring temples to this village. It is famous for the Arattupuzha Pooram Festival held in March - April every year. During this festival, idols of deities from neighboring villages are brought to the temple at night in procession on caparisoned elephants. This colourful festival attracts a large number of people from different parts of the state. The final pooram is conducted with caparisoned elephants bearing bright coloured umbrellas and parasols, presenting an unparalleled spectacle. The temple ensemble lends a majestic tenor to the extravaganza.

Pooram originated during the reign of King Sakthan. Earlier Arattupuzha Pooram was the main Pooram in the land. It was considered to be the meeting place of all the Gods in the world. But, once it so happened that, Gods in Trissur could not participate in Arattupuzha Pooram due to heavy rains and floods. So, in order to save the face of his land, the King started a Pooram in Trissur itself. He did it in such a grand scale that it soon occupied the primary slot. But the pity is that even there are no clear documents on its origin.

The famous Ayyappa temple at Aarattupuzha is just 14 kms from Thrissur, and celebrates its annual pooram festival during March.
