The Lord Ayyappa temple at Sabarimala, 80 kms. from the Pathanamthitta district head quarters, is a National Pilgrim Centre. This famous shrine of Lord Ayyappa is surrounded by hazardous hills like Karimala and Neelimala. Devotees visit Sabarimala after undergoing 41 days of ‘Vritha' i.e., self-imposed devotional penance. They, with irumudikettu (bundle with offerings to Ayyappa) on their head, climb the mountain ranges and cross the forest bare footed repeatedly chanting ‘Saranam Ayyappa' which means we seek refuge in Ayyappa. This is probably the only famous temple in Kerala, which does not restrict anybody from visiting it for not being a Hindu.

The synagogue at Fort Kochi, constructed in 1568, is the oldest in the Commonwealth. Destroyed in a shelling during the Portuguese raid in 1662, it was rebuilt two years later by the Dutch. Mid-18th century hand-painted, willow patterned floor tiles from Canton in China, a clock tower, Hebrew inscriptions on stone slabs, great scrolls of the Old Testament, ancient scripts on copper plates in which the grants of privilege made by the erstwhile Cochin rulers were recorded etc., are articles of interest here.
