Between the months of September and October, Kolkata celebrates the Hindu religious festival of Durgapuja on a grand scale. Organised by local clubs and neighbourhood voluntary associations, approximately 2,500 temporary structures – pandals – are built for the worship or puja of the goddess Durga and her entourage. Of these about two thousand occupy the city’s public spaces: streets, parks, green islands, and vacant lots. A large number of the pandals are finely engineered structures that are fabulously decorated and attract hundreds of thousands of visitors each day of the festivities. It takes anywhere between three months to three days to build these pavilions. After five days of festivities the pandals are dismantled and the clay deities destroyed by immersing them in the Hooghly River or another nearby body of water.
