Aranmula, in Pathanamthitta district, is famous
as one of the five temple towns like Guruvayur. Other major temples associated
with the worship of Lord Krishna are those of Trichambaram, Tiruvarppu and Ambalappuzha.
Lord Parthasarathy is the presiding deity of the Aranmula temple. There are
five ancient shrines around Chengannur, sanctified by the Pandavas. They are
at Aranmula (Arjuna), Chengannur (Yuddhishtra), Tiruppuliyur (Bheema), Tiruvanmandur
(Nakula) and Tirukkadittaanam (Sahadeva). The Tamil hymns of Nammalwar of the
1st millennium CE glorify this legend.
