Pilgrims wear black clothes and observe a strict period of fasting and abstinence before they make the trip to the temple. On an auspicious day during the pilgrimage, a light (Makara villaku) is seen on an adjacent hill, signifying the presence of Ayyappan. Young girls and elderly women also make the journey to this holy pilgrimage destination in Kerala.

Vadakunnanthan Temple:
Located in Trissur district, this is the venue of an annual temple festival. In this grand event, two rows of magnificently decorated tuskers, stand facing each other, while drummers beat out a traditional rhythm and representatives of the temples raise colored parasols over the elephants, bearing the images of the deities of neighboring temples. It is both an intense religious event and a colorful tourist attraction in Kerala that concludes with a grand display of fireworks.

The temple at Varkala, which is also known for its beautiful beach, is an important pilgrimage destination in Kerala. Devotees come to visit the shrine of the social reformer Sree Narayana Guru, who brought about the unrestricted entry of all castes to all temples in Kerala.


Churches:

St Francis Church:
This historic church in Cochin was built by the Portuguese in 1510. It was here that the body of the Portuguese explorer, Vasco da Gama, who opened the sea route from Europe to India, was placed before being taken back to Portugal.

Niranom:
This well-known Christian pilgrimage destination in Kerala, is believed to be one of the 7 churches established by St Thomas when he visited Kerala in 52 A.D.

St. Mary's Church:

Jewish Synagogue

Cochin:
Located at Mattancherry in Cochin (Kochi), this synagogue built in 1558 and later restored and enlarged, has a clock tower and is decorated with blue and white Chinese tiles.

Mosques:
There are many historic mosques in Kerala. Some of these include the Juma Masjid at Palayam Trivandrum, the mosque at Kottakal and the mosque at Kanjirapally whose Mullah is a part of the annual ritual at the Hindu pilgrimage destination of Sabarimala, because of its association with Vavar, the Muslim companion of Ayyappan. One of the striking features of traditional mosques in Kerala is the absence of minarets. Since houses were spread out, the muezzins call was ineffective and therefore minarets from which muezzin could call the faithful to prayer were dispensed with and the roof of the mosque followed the traditional tiled roof construction of Kerala mansions, to cope with the fierce monsoon rains of Kerala, India
