"Roshnai Gate" (Urdu: روشنائی دروازہ) or "Gate of Lights" is one of the thirteen gates within the Walled City of Lahore in Lahore, Punjab, Pakistan. It was the main entry point of the Rulers and the other nobles during the Mughal and Sikh Periods. Its extended height and width is testament to its use by emperors' caravans of elephants. Since the Ravi river once flowed alongside the northern wall of the Lahore Fort and the Badshahi Mosque, the gate was profusely illuminated during night to aid travelers. It is for this reason that the gate has been named as “Roshnai Darwaza” or the “gate of light”. It is considered to be the oldest of Lahore's gates, and is only gate that has been preserved in its original shape.
