About the location (from here):
The Gandhi Memorial Museum at Madurai has been built and organised by Gandhi Smarak Nidhi. The beautiful building in which the Gandhi Museum is now located has an historical background. The building was known as ‘Tamukkam Bungalow’ among the local people. The term ‘Tamakkumu’ or ‘Tamagamu’ is a telugu word meaning a ‘summer house’ or a building having a high roof supported by pillars without walls. The drawing room of the Tamukkam Bungalow which is constructed on the top of a square mound of earth about 5 metres high with a masonry dome of about 7 metres diameter was a great bulding. It is accepted as a building probably constructed by the Nayak Queen Rani Mangammal, as evidenced by a letter written to her in 1700AD. Later, this was made under the occupation of the Nawab of Carnatic, the East India Company and a few others. Finally, the palace had remained for many years as the official residence of the District Collector of Madurai. It was in the year 1955 that the palace with about 13 acres of land was gifted by the Tamilnadu state Government, to the Gandhi Smarak Nidhi for the purpose of housing Gandhi Memorial Museum. Besides major renovation to the original building, a complete new wing was constructed for the library as also several other buildings and an open air theatre.
