Golghar granary, Patna : It is built in 1786 by Captain John Garstin of British Army at Patna in Bihar. The state experienced severe famine in 1770. The structure is 29 m high and 3.6 m wide at the base. A spiral stairway winding over the dome to top, which has a breathtaking view of the city. The spiral staircase was designed to facilitate the passage of the coolies, who had to carry grain bags up one flight, deliver their load through a hole at the top and descend the other stairs.

The bizarre Golghar or silo was constructed at the behest of Warren Hastings. It is also noted for its echo. But it is doubtful if it was ever used for the purpose for which it was built.
