Kurmun has two old temples, the Ishaneswar Shiva temple with a lingam in the shape of a trishula and Kalachand Dharmaraj temple in Duleypara. Earlier, Kurmun used to celebrate two Gajan utsabs - Ishaneswar Gajan in the Bengali month of Choitro and Kalachand Gajan during Buddha Purnima. Now there is a combined Gajan festival in Choitro, celebrated by all castes in the village. In the earlier days there used to be a dance with a nara mundo (severed human head), that was collected from a dead body and painted in bright colours, but that has now been discontinued. In the Ishaneswar Shiva temple there is an old stone idol of Saptamatrika Indrani. It is a rather unusual combination of Shiva and Shakti worship.
