Lucknow

Lucknow is located in Uttar Pradesh in the northern part of India.

The Bara Imambara is a monumental, three-storey assembly hall of the Shiites from 1784.
The vast interior hall is 50 m long and 15 m high. It has no pillars and is an architectural miracle.
A huge labyrinth is the most fascinating part of the complex.
Plenty of interwoven corridors make it impossible to maneuver, unless you are a guide. The structure also carries sound through its walls.
Chhota Imambara (small house) is a mausoleum in Lucknow.
