Lal Darwaza also referred to as (Khooni Darwaza) is located on the Bahadur Shah Zafar Marg in Delhi, India. It is one of the 13 surviving gates of Delhi.
The Gate was built during Sher Shah Suri's reign as one of the two gateways of Purana Qila. It was known as the Kabuli Darwaza as caravans coming from Afghanistan passed through it. It came to be known as Khooni Darwaza during the Mughal reign due to various tales of bloodshed at the gate, in addition to the practice of displaying criminals' heads there. The gate is 15.5 m high and built with Delhi quartzite stone.
