The Golghar is a massive granary devised by Captain John Garstin of Bengal Engineers and constructed in 1786 in Patna, the capital city of Bihar. The depository, having a capacity of 140000 tonnes, was built after the orders of Warren Hastings who was the Governor-General of India at that time. It was just part of a plan to store grains in case of famines with the idea of building a chain of storehouses, but ultimately only one was made, the Golghar. <br><br> It is a dome shaped structure reaching up to a height of 29 metres. The top of the Golghar can be reached using one of two 145-step spiral staircases. The access to the apex is made spiral in order to make it easier and faster for workers to reach there. There is only one door to the building, on the south. <br><br> The structure was constructed using brick and lime mortar. It stands on a platform about 40cm in height. The wall thickness at the base is 3.6m. The pillar-less beehive-shaped structure was designed by John Garstin of the Bengal Engineers, part of the East India Company's Bengal Army. <br><br> Apart from being a repository, this simple yet stunning structure presents an amazing panoramic view of the entire city and the nearby Ganges.
