Attukal Bhagavathy Temple is popularly described as Sabarimala of the Women, as women form the major portion of devotees. The Goddess in the temple of Attukal is worshipped as the Supreme Mother, creator of all living beings and the mighty preserver as well as destroyer of them all. The pilgrims from all over the country, who visit Sree Padmanabha Swamy Temple and worship the Lord, do not consider their visits complete without the visit to the shrine of the supreme Mother Attukalamma. Vishnumaya took the incarnation of Bhagavathy to annihilate the evil and protect the good in the world in the present Era namely Kaliyuga.
According to mythology, Attukal Bhagavathy is supposed to be the divinised form of Kannaki, the famous heroine of Chilapathikaram, written by Elenkovadikal, the Tamil Poet. The story goes that after the destruction of ancient city of Madurai, Kannaki left the city and reached Kerala via Kanyakumari and on the way to Kodungalloor took a sojourn at Attukal. Kannaki is supposed to be the incarnation of Parvathy, the consort of Paramasiva. The hymns of the "Thottampattu sung during the annual temple festival, are based on the story of Kannaki. Moreover, architectural depictions of Goddess Kannaki seen on the Gopuram temple substantiate this mythology.
The temple structure is a harmonious conglomeration of both Kerala and Tamil styles of architecture. The beautifully carved figures of Mahishasuramarddini, Goddess Kali, Rajarajeswari, Sree Parvathy with Lord Paramasiva and various other depictions of the Goddess in and around the temple are undoubtedly the work of a gifted artist. Equally well presented around the corridors surrounding the temple, are the depiction of various other Gods and the epic stories of the ten incarnations of Lord Vishnu viz., the "Desavathara". On either side of the elegant front gopura - are the icons based on the story of Goddess Kannaki. On the southern Gopura, the puranic story of "Dakshayaga" is depicted in sculptures. The decorated gate at the entrance of the temple is by itself an excellent example of architectural beauty.There are two idols of the Goddess in the sanctum sanctorum. The original idol is preserved in all its pristine beauty covered in ornamental gold embedded with installed stones. The second idol of the Goddess is installed besides the original one. Within the temple corridors are also installed carvings and sculptures of Lord Ganesan, the serpent God and Lord Shiva. At the centre of the Sanctum within the Sreekovil, at a consecrated spot is installed the idol of the Goddess Attukal Bhagavathy emanating light and lustre to all.
The Pongala Mahotsavam is the most important festival of Attukal Bhagavathy Temple. The offering of Pongala is a special temple practice prevalent in the southern part of Kerala and some parts of Tamilnadu. It is a ten-day programme commencing on the Karthika star of the Malayalam month of Makaram-Kumbham (February-March) and closing with the sacrificial offering known as Kuruthitharpanam at night. On the ninth day of the festival the world famous Attukal Pongala Mahotsavam takes place. The entire area of about 5 kilometre radius around temple with premises of houses of people of all caste, creed and religion, open fields, roads, commercial institutions, premises of Government offices etc. emerges as a consecrated ground for observing Pongala rituals for lakhs of women devotees assembling from different parts of Kerala and outside. The ceremony is exclusively confined to women folk and the enormous crowd, which gathers in Thiruvananthapuram on this auspicious day is reminiscent of the Kumbhamela Festival of North India.
