documenting our time
Rumi means Roman(referring to Roman empire). It is believed that the gate is called Rumi Darwaza, simply because it was modeled after the gateways of then Constantinople or Modern Istanbul which during that time was the capital of Byzantine empire(Rome).
The Rumi Darwaza, sometimes known as the Turkish Gate, in Lucknow,India, is an imposing gateway which was built under the patronage of Nawab Asaf-Ud-dowlah in 1784. The Rumi Darwaza, which stands sixty feet tall, was modeled after the Sublime Porte (Bab-iHümayun) in Istanbul.
It is adjacent to the Asafi Imambara in Lucknow and has become a logo for the city of Lucknow. It used to mark the entrance to Old Lucknow City, but as the City of Nawabs grew and expanded, it was later used as an entrance to a palace which was later demolished by the British insurgents.
