Chattar Manzil is near the Begum Hazarat Mahal park, on the banks of the Gomti. The United Service Club, otherwise the Greater Chattar Manzil, was once a king's palace. Under the existing river terrace was the 'ground floor'; below that were the tykhanas, cooled by the waters of the Gomti which lapped against the outer walls. Considering their size, surprisingly little is know about the Chattar Munzil Palaces. The name comes from the gilt chattars or umbrellas atop the two main buildings. On November 19 when Sir Colin Campbell decided finally to evacuate the Residency, the way to freedom lay through the Chattar Palace. Today this building houses the Central Medicine Research body. The Lal Baradari was also the part of Chattar Manzil and was built as Coronation Hall and Durbar Hall.
