In the cluster of temples at the Red Fort end of Chandni Chowk, the scarlet Digambara Jain Temple houses a fascinating bird hospital established to further the Jain principle of preserving all life, with a capacity of 10,000. Only vegetarian birds are admitted (up to 60 per day), though predators are treated as outpatients. Remove shoes and leather items before entering the temple.
Nearby, the 18th-century Sisganj Gurdwara marks the the martrydom site of the ninth Sikh guru, Tegh Bahadur, executed by Aurangzeb in 1675 for resisting conversion to Islam.
