Right on the Mathura road near Maulana Azad Medical college
stands a double-storeyed imposing gate, built largely with grey stone, red
stone having been used in the frames of its windows.
It is believed to be one of the gates of Sher Shah's city of Delhi, although no remains of a city-wall have been traced in continuation with it. Another surviving gate of the city has been described earlier.
It is also known as Lal-Darwaza and has derived the name 'Khuni-Darwaza' (bloody gate), from the tradition that two of Bahadur Shah's sons were hanged here.
