The two Chattar Manzils near the Begum Hazarat Mahal park, on the banks of the Gomti were Royal pavilions. The name comes from the gilt chattars or umbrellas atop the two main buildings. The Greater Chattar Manzil was once a king's palace. Under the existing river terrace was the ground floor with the tykhanas (cool underground rooms), cooled by the waters of the Gomti which lapped against its outer walls. Considering their size, surprisingly little is known about the Chattar Manzil Palaces. 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.
