If you are slightly interested in History and you are in Pune then this Museum is to be first on your list. Would be good to prepare a bit for this, surf a bit to know why this is special and how a one person army has collected and restored these artefacts. What is available for public to see is just quarter of the exhibits.
I have been in Pune for the past 3 years and when I am looking for something to do, this is one of the places one can easily go for a couple hours.
The immensely highlighted Mastani mahal is losing its sheen, but the musical instruments, the textile gallery , the utensils gives immense joy and respect to the collector.
